I have installed Cairo Dock on Linux Mint which works great except when I go to remove an item from the dock it freezes.
This is because I haven't confirmed the removal of the button from the dialog box. as per this page - http://glx-dock.org/bg_topic.php?t=6145
The problem is 90% of the time I have absolutely no idea where this dialog box is. Sometimes (rarely) it will show on top of all my open applications and I click "Yes" and we go happily on our way, but usually it won't show, and minimizing all applications doesn't reveal it. I've even tried removing an item from the dock with no applications open at all and the dialog box won't show even on top of the desktop.
