I'm running on Windows 7 x64 and have a user toolbar in SlickEdit. After installing RC1, many of the toolbar buttons are missing. Tooltips still are displayed when I hover over where the button should be, but nothing happens when I click the toolbar on the "invisible" button.
I initially renamed my existing 22.0.0 config directory and let SlickEdit upgrade from my 21 config and thought it might be an upgrade problem. So I switched back to my 22.0.0 beta 3 config directory and still see the same thing.
