UI fault when starting minimized

[MerlinTheGreat]

When starting minimized, the user interface goes wonky. Every time. (see attached picture)

I started PMPC minimized (shortcut) after which I clicked the taskbar icon to watch what it was/would do.
The scroll bar was missing and so were the buttons at the bottom to rescan or start the updating.
After ending the programm and restarting it in normal mode, the interface was ok.

Not an error that is lifethreatening, but still anoying.
Please look into that.
