Hello there! first post btw :)
I've been using this program for a couple months and I'm pretty happy with it so far. I'm cintiq 24HDT user, so I decided to upgrade and buy a second monitor to display the navigator and whatever reference images I need, but after installing it the touch commands like pinching to zoom or rotate stopped working and now it only lets me pan the canvas with two fingers. I had similar troubles in the past, but restarting the tablet service driver, or painter itself (or both) fixed the issue.
Since I've been searching around the web and I didnt find people with this or a similar trouble, I suppose that I'm missing some hotkey or some interface button that I pressed by mistake, but cant figure it out...
hmm on response on this issue, if someone ever experienced something similar must say that UNchecking the option "use multitouch commands (requires wacom device)" makes it work again, (I find a bit of lag when rotating or zooming), while checking this option reverts it to the useless locked option. So I guess I'll try resetting preferences...
Thanks for keeping us informed Abishai, it may help others.
Well I have another update on this: I've performed full reinstallation of painter, preferences etc, wacom drivers and what really fixed my problem was unplugging the 2nd monitor :S Now I have smooth rotation/zooms again. So, looks like drivers/painter bug to me. Lets hope some developer takes note on this issue, cheers!
