lwf - max vieport crash?

hi all
since i started working on lwf i have many max crash when switching from wirframe view to shaded view , when deactivating all maps (view - deactivate all maps) the problem usualy solved.
does anyone elese had this problem?
is it a known issue?
Gili

I too get crashes in Viz when changing some scenes from Shaded to Wire Frame. However, I don’t use LWF so I guess it’s something else.

Could it be video driver problems?

Best regards,
Vlado

I am using ATI

it could be but i never had before i started using lwf.
