I'm having some odd problems with Poser 7, which seem to have developed overnight.  Render times suddenly greatly increased though I'm doing nothing different and using the same lights and same characters.  Poser sometimes puts the wrong texture on the character, etc. when I click the texture in the pose directory.  Sometimes Poser can't find a texture, and I have to hunt through the directory for it--though it was in the right directory all along.   And when I render objects, the color sometimes comes out odd for no reason and no change in the material setting.

It seems like Poser is confused.  Corrupted poser files?  A virus?  I'm not sure what to do.  My harddrive is also nearly maxed out, and I wonder if that could be the problem.  I have a lot installed in Poser.  I'd also downloaded and installed some free props a few days ago, and I wonder if that could be causing the problem.
