Hi Ho, EnglishBob suggested that I should take a look here, since there's a possibility that the problems might be (somehow) Mac related. Before I start I must say that I hardly work with the PC Poser (except for specific testing) and although I occasionally code for the PC, I'm not too familiar with low level stuff. In a word: I'm just guessing here... Having said that, a couple of ideas: 1) I don't know if the "file type" filtering under Windows is a high level system service, or a low level custom filter - on Mac it is low level (as soon as a selector popup gets involved). I really don't know about the PC, but on Mac there is a difference between "all files" and "any file". "all files" means "supported by the application", which is simply the whole set of individual types further below. "any file" means absolutely every file - if it's the same on PC, then it would make sense that .pct won't get listed, because it's not on the remaining list. MetaC/CuriousL are using a porting library to create the PC Poser - it might be possible that this "all files" entry mimics the Mac behaviour. 2) Poser's texture searching is 100% voodoo, and I gave up to understand it... and the Mac version of it differs completely from the PC version. Part of it is even hard-coded into the compiled code, and it changed with every beta version and between localizations. Further, the PC version seems to be especially unreliable - there once were threads about odd behaviour with Poser's prompting for missing bumpmaps. On some PCs you were able to select a different filetype, on others it locked Poser. We never worked that out. All I can say is that the reflection maps never seemed to cause trouble on Mac. 3) This might be a clue to follow: To my knowledge there is a significant difference between Poser with/out QuickTime - and I believe that (at least some of) the unpredictable behaviour on PC is due to this. Poser seems to be able to open a certain subset of PICT format on its own (like the thumbnail data), but obviously not the full set. But it uses QuickTime services to support additional filetypes, so this might be the difference that triggers some strange effects. To add more confusion - some PC people will have the QuickTime kernel, but don't know about it: If you uninstall QuickTime, you get a warning that uninstalling the kernel might cause trouble to your system. If you decide to leave it (at that point), then it will leave the graphics engine on your system (that is used by Poser) and only uninstall the user front end. In other words: Poser will continue to use its features, but the user believes he got rid of QuickTime. And to add much more confusion - some "still images" services are not included with the "simple install" on PC (different to Mac), but only with the full/authoring install, or available as a custom option. From my (limited) experience with the PC Poser, I must say that Poser runs better with QuickTime installed. Hope that helps, MartinC
