Esther, I remember the Keynote when Steve (Jobs) talked about OS9 and mentioned that it's considered a dead OS. I don't think that what Apple did in this case was deliberate, but their way of saying that OS9 will no longer be updated for additional compatibility in Classic mode. Since many of the underpinnings and functions of Panther are much more advanced than Jag, this is where the incompatibility comes in. As far as what you've tried, I admire your effort, but the problem runs deeper into how Classic interacts with Panther. The flickering menu bars and speed issues don't point to a bad video card, but a poor interaction between a very memory intensive application (Poser) and a very high-end OS (Panther) with a lack of additional integration thrown in. Apple has basically washed their hands of Classic. I hate to say it, but it appears the only way to fix it is to either boot OS9 or upgrade. I can live with what's happening, but it sounds like your condition is much worse than what I'm experiencing (I'm not getting any kind of speed loss). I'm in the process of trying Poser5 and since I do so much additional work in Photoshop and Painter, it probably won't affect me since I only use models and occasional prop armor, but your situation sounds a little more tough. The only way around it is to work in 9 and then go back to X when you're done. Oh and I may not be seeing the speed issues since I have a dual drive and my OS9 and OSX systems are on different drives (and I do run Poser on the OSX drive). Maybe there's something to that after all. I'm really sorry we couldn't solve this and I urge you to hang in there. It could be worse! Andy
