Laucha, you're not alone. I'm getting the exact same error message. At first I thought it was because I futzed with the terminal, and changed the default format and location for screen grabs, but now having returned them to the defaults, I still get the error message. And as for the "insertion point" explanation, this can't be right anyway. Grab captures image data from the screen, not text data... a fix or explanation would be great if anyone comes across one...
