I love it. I made three and accidentally erased them all. Then I figured out to just do a screen capture rather than trying to save it directly. I only wish there was a way to drag the mouse without painting.
You can... to an extent. A right click will bring up the flash menu, allowing you to hover over to a new spot. But left clicking somewhere else will still make a thin line to that spot.(Unless you're Mac, then you have to apple+click or ctrl+click or whatever, I guess.)
ALSO, pressing any of the F buttons (e.g., F1) will bring up a signature and some info, BTW.
