What happens?
When I minimise MediaMonkey and then maximise it again by clicking on the taskbar button, an error message like this shows up:

When I click away the error message the top right corner changes it appearance a little:

The minimise button is changed for a maximise button and I am unable to maximise MediaMonkey by any means. Clicking the maximise button results in MediaMonkey becoming a little tray in the bottom left corner of the screen:

Then, the only way to fix the bug is closing MediaMonkey using the Windows task manager and restarting it.
How to reproduce it:
- enable "album art with details" mode
- rightclick on the cover of an album which has the artwork saved in an external file / in external files
- choose "Edit album art properties"
- remove all album arts
- confirm to delete files as well
- minimise and maximise MediaMonkey
Tests I have done:
- bug occurs on both of my systems
- bug occurs with plugins and scripts deactivated
- precise error message varies
- bug will always occur
Anyone has an idea on how to fix this bug? Does it only occur to me?
