[Mono-winforms-list] Windows Forms on Mac OS X

[Erik Renes]

Hi Everyone,
A short status update ...

Meanwhile I have succesfully installed cairo using macports, then I  
have dllmapped the libcairo to the one installed by macports by  
editing the config file in the Mono.Framework etc/ directory:
<dllmap dll="libcairo-2.dll" target="/opt/local/lib/libcairo.dylib"  
os="osx"/>

This caused the windows forms application to work, however, only in  
the second instance of X11. Let me elaborate:
First I start my test.exe using 'mono test.exe', then X11 pops up in  
the dock and does not do anything. If I quit the running X11 instance  
(right click on X in the dock and click Quit) it immediately comes  
back after closing down. Directly after, the messagebox is being shown  
as expected.

I can now run Windows Forms apps normally, however if I close this  
second instance of X11, I have to repeat the procedure to get it  
working again.
Now for development this is not so much of an issue, but runtime  
deployment I don't think any user would want to do this just to run  
one app.

Does anyone have any suggestions that I can try to make it work as  
intended? (or is this intended?) I have read something about a native  
driver for winforms, is it enabled by default in Mono 1.2.6 on Mac OS  
X? If not, maybe this is something for me to try out, if anyone could  
tell me how to enable it?

Best Regards,
Erik Renes
