Happens ever time windows boots.
Shortcut in Startup folder has "run minimized" selected. During startup AltBinz window is visible and never minimizes. Visible means window but no content (blank container). Need to click on taskbar icon to make the visualisation normal and then can minimise manually and then AltBinz behaves as one would expect.
If I close AltBinz and run the shortcut manually (rather than automatically as part of startup sequence) then blank window appears per the above for a few seconds and then AltBinz will minimize as expected (ie the problem ONLY happens at windows boot).
