Hello! I am running IM 3.5 on a OS 10.2.4, 800 mhz, 1gig of RAM.  
 
IM works great until I extract textures, then it quits on me. I have read that others have had this problem and am wondering if a solution has been found?

Hello,
 
  We could reproduce the problem on our side. It's related to the size of the original images and also to the texture to generate (one side larger than 2048 causes pbs).
We are working to fix it, and will add a new version (patch) in the download section.
It's a matter of days ...
 
Thanks for the feedback,
 
Stef
