[solved] Problem at Skining with 1 Window

[-SubZero-]

I made my onw TS3 Skin and i got 1 problem with 1 window (File Transfer).
To see it: FIle Transfer picture
Everything else work´s fine but this window got problems with this skin, so does any one knows it´s name (for example: Qwidget#FileTransfer), so i can set it: background-color: #000;

Thx for every Help
