Pxe 0.8 Crash on heavy graphic

Hello,

I have some problem with few people on pxe 0.8, with ICA Client 7.1.
I have a squash pxe  image. Everything goes well and sometimes, with big 
pictures under powerpoint or IE 6, the X server goes down. 
No errors in the XFree log so I don't know where is the problem.

The squash image is near 9 Mo, and the computer have 32 or 48. The graphic 
cards are S3 Trio or Neomagic (Dell series Gs/Gn/G1).

Any idea ?


Best regards,
Sébastien Dagnicourt.
