In the "change menu object" dialog, there's a small UI problem: Normally, if I select a text in a text field it stays selected so that I can paste with the middle button. This is true for example for the "command" text field. But this doesn't work for the icon field, it's automatically deselected which makes copying a bit hard (you have to use Ctrl-C and Ctrl-V as in Windows).
Hmm. I guess this has to do with the validation of the image that occurs when you change focus. Not sure this will be easy to fix though. Reducing priority and severity a bit.
It was simpler than I expected. Fixed in CVS. Thanks.
