I experienced the phenomenon which suggests that installation of QuickTime causes this problem. And performance was recovered by uninstallation of Quicktime. I experienced this phenomenon with QT5 and QT6. Have you experienced the same phenomenon?

I don't have a problem with P5 on XP with or without QT installed.

You may want to update your winxp, some of those updates give you quite a large boost in performance.

same as Sam. I have no problems with P5 on xp at all. I don't have QT installed currently but have in the past and had no problems

QT has a TSR client that can be disabled in the msconfig settings from starting on boot. The issue is QT, not Poser or winxp.

I have quicktime, poser 5 and XP and no problems (touch wood) :) Although I do disable everything I consider unnecessary before bootup using msconfig.

QT has given me so many problems on a number of platforms (with and without Poser)that I refuse to install iy again.

I feel the same way about RealPlayer.

Thank you for responses.

About the resident process of QT, I also saw on the forum of Apple.
Seemingly, this process will be revitalized like a zombie.

Although CPU should not usually be used for this type of process,
does it influence the performance of other tasks?
I have not experienced this problem in Win2K.
It is mysterious.

Moreover, is XP correction patch which is likely to be related to this released?

So what problem are you talking about?

I am sorry. Since the same subject was contributed before, I have omitted the description of this problem carelessly. The most remarkable problem is that the displaying of icons at the time of the change of a library becomes very slow. Although it is dependent on the number of icons, it requires about 4 times as many time as this compared with case of no installation of QuickTime.

It might be that you have set Quicktime to normally open png. I have it installed, but only for .mov files.

About the relation of files and APPs, I am nervous. Therefore, I always change a default setup of QT installer, and am made to remove relation except mov, aiff, and pict.

I at least have experienced this phenomenon in two different machines.
My acquaintance has also experienced the same phenomenon.
It is strange that users with this problem and users without this problem are exist.

I am not going to install QT until the solution of this problem is found.

Thank you all

I've never liked QuickTime. It just seems too oppressive, wants to take over functions I've used other programs for. Besides, I don't seem to actually use many things that require QT. So I avoid installing it.

The newest version of QuickTime was pre-installed on my new computer. When I un-installed it and cleaned the registry (over 40 entries),I noticed a HUGE change in poser. I went from waiting 10-15 sec for the icons to show when I changed library folders to being instantaneous. Poser in general seemed a bit faster overall. I didn't see any changes in any of my other programs,so I would say there is some relationship between Poser and QT.... Perhapes some old codeing leftover from the original Poser that was made for Mac? SWAMP

I agree with the SWAMP's idea (some relationship between Poser and QT).

I found out the behavior which suggests existence of the active relation between Poser and QuickTime.

QuickTime cannot be uninstalled while Poser5 is running. (The message that there is a program which is using QT is displayed) . By terminating of Poser5, I was able to uninstall QuickTime.

Then,,,, I installed QuickTime, with the state maintained where Poser5 is running.
Then, the performance was maintained good until Poser5 was rebooted.
The performance got worse again after rebooting Poser5 (not a OS).

This behavior is suggesting that Poser5 try to use a QuickTime module actively itself if QuickTime was installed, I think.
The cause of this problem is not kinds of DLL-overwriting but a behavior of Poser5, I think.

Well, note that poser does use common library elements that are a part of quicktime for various aspetcs of interface and animation -- always has. But they are installed by poser itself an installation time. These same elements are referred to by the TSR agent, creating a dual reference. These common library elements are present still in the current QT version (and the similar itunes component) for backwards compatibility. Note that I have both installed. I use QT in my media authoring, so it's somewhat important. I do not have the tsr enabled, and my library load time is roughly about a half second (and each of my runtimes is still quite large). I can speak only to the experience I've had across a range of systems, and will note that every system has it's own kinks and quirks once it's been used. I should also note that I have the two programs installed to different physical drives (Poser has it's own entire drive), and that QT only has association with MOV files.

maybe this out of topic , but try to www.blackviper.com he have tweaked registry and services for boost win xp per formance

Although I have installed QuickTime as the minimum option, I cannot find a TSR process.
Please teach me how to set TSR to disable.

I have noticed requiring QuickTime, in order that Bryce may treat PNG. This means that QuickTime is required for TurboImporter by DAZ.
