Comment (by jscipione):
This bug is not directly related to icon resizing, but by any action that
triggers a deadlock due to rapidly deleting and rebuilding the fExpando
menu bar. I'm not surprised that the above command, which turns the
expander arrows on and off repeatedly, causes the Deskbar to get into an
invalid state. I have a branch pending that fixes the problem (I hope) by
building the menu bar object one time in the constructor and then only
updates the list inside rather than deleting and rebuilding updating the
whole menu bar. I have this working pretty well, there are just a few more
cases that I need to work out before it is ready to go. Not only will this
fix this bug but should make changes to Deskbar noticeably more
responsive.
