Description Michael Gorse 2009-03-16 19:19:42 UTC 
Running mono-uia can sometimes make an application take much longer to draw the user interface.  I suspect that this is particularly the case when there are many list items in a list for instance.

Repro:
1. Install wf-apps.
2. Time reportBuilder without mono-uia loaded.  Allow the app to start, then press alt+f4 to close.
3. Time ReportBuilder as before with mono-uia loaded.

Result:
The first time takes 1.2-1.5s on my machine.  The second time takes 9.5-10s.
