Hi Volker,

first of all thanks for the really quick fix!

Now I did run into another issue, when doing the same action (opening
settings on a ikvmc jDownloader.jar):

System.ArgumentException
Control does not support transparent background colors

I did resolve it, not sure how good or bad these changes are...

*Fix1* toolkit-0.95.cs Zeile 83 (UndecoratedForm Constructor):
changing
            SetStyle(ControlStyles.UserPaint | ControlStyles.ResizeRedraw,
true);
to
            SetStyle(ControlStyles.UserPaint | ControlStyles.ResizeRedraw |
ControlStyles.SupportsTransparentBackColor, true);

or *Fix2 *toolkit-0.95.cs Zeile 2759 (setBackground)
Changing
                NetToolkit.BeginInvoke(delegate { this.control.BackColor =
J2C.ConvertColor(color); });
to
                NetToolkit.BeginInvoke(delegate { this.control.BackColor =
Color.FromArgb(255,  J2C.ConvertColor(color)); });

Like I said before the gui is not important for me (but nice to have for
debugging). So I have no problems with ugly L&F ;)

Settings are now working fine, thank you!,
Matthias
