[scribus] use of "Hand" causes Scribus to flip out

[Cat]

Maybe not flip out, but sometimes when I use the hand tool (Spacerbar) to skootch my document around, nothing happens, but the white arrow tool will begin blinking for upwards of a minute or more.

clearly, I've done something wrong, but is this a bug? should Scribus simply throw out a dialogue saying "can't do that" and not be paralyzed for so long?
