I tried a really quick google search on this and couldn't find anything, and I'm kind of in a rush to finish off the project in Photoshop so if this is answered somewhere already, please point me me there This has only happened since I've upgraded to Leopard. When I make a stroke with the brush/clone tool (maybe others too...but I haven't used them yet) it would literally take 15-20 for Photoshop to show the stoke/change and the entire program would be unresponsive while waiting. At first I thought that this was a Photoshop issue so I upgraded from 10.0.0 to 10.0.1 but problem still persists. The I also downloaded the "Leopard (improved)" drivers for the Wacom tablet but that doesn't help either. This lag/unresponsiveness only occurs when using the tablet, when using the trackpad Photoshop is fine. thanks A LOT to any help. EDIT: ok, one little thing that I describe incorrectly. The stroke shows as soon has you make it, the lag starts after that. If you make any strokes during that lag period, it won't show until after the lag has "cleared up" (15 secs or so). After that 15 sec period, the program will "unfreeze" until you make the next stroke.
