[Mono-winforms-list] ToolStripDropDown + UserControl

[Alex Shulgin]

Hi,

I'm trying to add some custom control to ToolStripDropDown using 
ToolStripControlHost.

This works fine with .NET, but with Mono (2.2) the control is always 
resized to 22 pixels tall...  Too bad I can't find a workaround for a 
few days now.

Any help & suggestions are much appreciated. :)

Below is sample code to demonstrate the problem.
