I've had some weird stuff happen recently... I usually want arrowheads at the end of arrows I add, so I always uncheck Start Arrow and check End Arrow. But the last couple days the arrowheads have been showing up at the start anyway.
Most of the time... sometimes I can exit SSC and start it back and it's fine.
Also it seems like when the arrows go wonky, I can't copy the image to the clipboard - I click on the image and do a ctrl-c and the box says the object was copied to the clipboard, but there's nothing to paste when I'm in the other application.
I've just noticed it on my main work pc (win 7, 64 bit) and just now duplicated it at home. I don't know that I've used many arrows since I upgraded to 3.04.01 but I know it was working fine at some point before now, I'm just not sure when.
Definitely odd... maybe I can pull down the previous version to try? Although I would hate to give up the sweet cursor capture options...
