encountered a strange problem in perspective viewport of Maya 8.5 maya 2008 64bit version. When I create an object in the full perspective viewport, rotating the object several times (alt + LMB) and the screen will cease to be redrawn/refreshed(I cannot rotate the object anymore).
If I switch back to four viewport mode, then the perspective screen will be redrawn and reflects my last action on the object, but the problem will come back again if I rotate the obj inside the persp viewport.
This problem seems to happen only in XP 64bit environment, I cannot reproduce it in 32-nit XP. Does anyone has idea what possiblly cause this issue. Thank you.
