I am using a Radeon 3650 and the latest Catalyst software as of 30 minutes ago. 2009.0317.2131.36902
NET Framework version 2.0.50727.3074 Vista 32 bit
I am running two displays: Samsung SyncMaster 2343 BWX at 2048 X 1152 and Princeton VL173 at 1280 X 1024.
A few versions ago the desktop configuration would be stored and maintained after a power restart.
Version 9.4 does not do that. I have to change the primary display resolution to something lower and drag the secondary display to the #2 box and select extended desktop and save. Then I have to do it again at which time the second display picks up its part of the desktop. Then - third step - I have go back to primary display and reset to 2048 X 1152. Of course, if I have manually configured desktop icons at any time before previous power down, when the next power up occurs, I have lost the icon position to the default order. Frustrating to have to do this every time I power the system on.
Remember, didn't have to do this a few versions back - HOWEVER - the older versions were causing the primary display (2048 X 1152) to shutter at random and annoying times. Version 9.4 cured the shuttering once the extended desktop is set up.
