Evidently ATI is incorporating some of the driver issues from Vista to XP now. I contacted Uli at EF about it last month.

Use the 7.12 drivers, and in the poser ini in the documents applications folder make this change:

Here are the steps in a nutshell:
"Windows Vista owners with certain ATI graphics cards may notice that
Poser takes a long time to highlight the body part or prop that is moused
over (due to the long delay it may appear that items are not highlighting
at all.) This complicates the job of selecting parts to pose; the
situation can be greatly improved by editing the Poser.ini file to set the
PREVIEW_OGL_OBJECT_BBOXPICKING entry to 1 (from the default zero.)"

That resolved the issue here with the 7.12 drivers. I always update my drivers as soon as they are available, and ran into this weeks ago.. it drove me NUTS trying to figure out what was what, but fortunately, I had a poser guru I could ask about it.

So, install the 7.12 ati driver, reboot, and then make the ini change before starting poser up.. I didn't see any issues at all with P7 after that change.

Way too many people take way too many things way too seriously.
