Description Paul Webster

Build: I20101119-1108 4.1 SDK

Whenever my mouse moves over the area that can expand/collapse methods, I get the following error.  The implications is that the GC handle == 0 (but I can't see how that can be possible given the code).

Dani, what do you think?  This is restricted to 4.1, I can't produce in 3.7.

Please also fix bug 327837 while you're in that method.

The dispose call is no longer needed as the color will either be disposed by the engine or it's a system color.
