WinUAE 4.9.1 (using hidden switch -p96test 1), OS3.9 + MMULib
The other day I was so excited to test P963.3.0's new feature "different res screen dragging", but I've found it worked (with visible glitches) only on the very first reboot (I manually installed it with a simple "copy RamDisk:Picasso96Install/Libs/#? LIBS: ALL") coming from P963.2.3:

The strange thing is that on next reboots (even I quit and restart WinUAE!), "UAEgfx" driver crashes on boot with an "Illegal instruction" GURU
Rolling back to P96 3.2.3 solves the issue.
