I'm not sure if this is the appropriate location for this question, but I didn't see anything better...
I've noticed with the extensions I build for CS6 that Illustrator has a difficult time getting the mouse focus. Whenever an extension has the mouse focus, you have to click twice in the Illustrator UI in order for Illustrator to grab the focus back. It doesn't matter if you're clicking on the canvas, artwork, another tool or the file menu, it always takes two mouse clicks to do it.
It's not the just extensions I'm creating. This also happens with the Kuler extension, which comes with AI.
Is there anyway to get around this (bug) or are we just stuck with it?
Illustrator has an SDK forum… I think you post would be better answered there if at all?
