Thanks for that. I remember that it worked fine. I didn't typically have two monitors but now I often have the cintiq for drawing in various other apps, but especially for sculpting in Blender.

In any case, The fix should be:

1. that the bounds of the dialog should never exceed the bounds of the main app window, regardless of what the monitor dimensions are. It's a dialog; the main window is frozen anyway. The dialog should be over it. Really, get the physical dimensions of the main window display, center the dialog, "glass over" the rest of the window.

2. esc should always close a dialog, terminate whatever is happening. If there's a render or sim or whatever, esc stops it. Escape. It's right there in the word :D
