Winamp Main Window just a small badge in modern skin

I came to have the main window of Winamp in modern skin just as a small badge (about 30px height) with no possibility to resize. Functionality fine - appearance broken.

Changing the skin restored the main window, but back to modern skin it was a one-line-menu again. Research in forums brought up nothing helpful for me, just messing around with the config files didn't help.

For me this was helpful:

• open winamp
• toggle main window ON if necessary ("Alt-W")
• if necessary double-click to change from playbar to (what should be) normal window
• right-click on the remaining bar
• choose to see e.g. equalizer
• bar breaks at the bottom and shows remains of misplaced equalizer
• grab edges and resize

The new rectangle-information will be stored, winamp ist in normal shape again.

Hope that helps.
