Padshop Pro on X3d

 
I bought Padshop Pro in the Stenberg sale at the weekend and tried running it on x3d. It seems you get both the vst3 and vst2 versions installed however with the vst3 padshop pro version in Sonar the preset browser is missing from the middle of the bottom pane. You can still open presets from the top panel file-browser but you then lose the tree structure.
 
To get around this I’ve had to change preferences so that vst2’s aren’t removed from the synth browser if there’s a vst3 present, so I could run the vst2 version and have the preset browser.
 
I also noticed there seems to be an intermittent flashing behind the window (like an application momentarily appearing then vanishing) and both the vst2 and vst3 versions seem to frequently lose context or something and the interface hangs up for a several seconds when you’re trying to adjust the settings although the sound still works ok.  This isn’t a showstopper but it is a bit annoying.
 
Has anyone else found these issues?  Are there workarounds or reported bugs do you know?
