As the title suggested something in my system brings down PD11 64 bit ultra down periodically
(say around 10 minutes after starting up PD).
PD cannot even report this as it usually does when it crashes by it's own fault.
Window application event states ==> atimpenc64.dll_unloaded
I started noticing this recently.
PD has become unworkable by this.
- sw: catalyst 13.3 beta 3 (works fine in all games, even openCL is tested and benchmarked, has a fix for openGL)
Note do not use 13.3 beta 2 as this has an issue with openGL (not openCL)

Note that crash can happen even when PD is idling (start up PD default option full edit, do nothing, then minimize on desktop)
Note: I do have IE10 and email open while PD is idling.
Note: PD does not need to be idling, as I have it also when working with it. Win7 Ultimate, i7 930@2.8GHz, RAM 6GB, 2xSSD (raid 0), 2Tb data drive, creative X-fi, 2x ATI 5850 in crossfire mode, PD 11 ultra + color director
