File Manager does not open [1.22.2 SP1] [minor]

[ExZtEd]

Hello,

here my second and presumably nonrelevant issue:

If you open the File Manager by clicking the cupboard in the background the window will open normally. (1st time)
If you now click "Apply" the File Manager will close as expected.
If you click the File Manager again, it will not open but it's playing the sound for opening. (2nd time)

Clicking the File Manager again (3rd time), it will open normally.

There is nothing in the Logfile, so i did not upload it.
