Greetings Michael,

A couple of updates.  Screenshot attached. The added tab moves to the
current window. ESC causes the tab to disappear but does not discontinue
this mode. Also when the dialog poped up to request the timeout for
capturing the screen, the text field had a funny looking e in it and I
could not change the field value until I hit ESC.

For #2, when not in said #2 bug mode, shift-up/down acts as +/-.
Shift-left/right frame++/frame--.  ctrl-left/right roi.width++/roi.width--
although ctrl-up/down act as +/- and not roi.height++/roi.height--.

Bonus question/request:  Is there a way to move a really small roi with
the mouse.  Generally you grab the boarder or grab while the cursor is
totally with the roi.  But, alas, with really small roi(s) these don't
work.

Thanks,

Fred
