I tried launching on my iBook PPC G4 (with MacOSX 10.4.8 running 
X11.App with the latest bugfixes from Apple) a simple winforms C# app 
with Mono 1.2 rc 0 and I got the error reported below.

Actually the 
only Mono release that allowed me to run this application was Mono 
1.1.14; every other version I tried in the past could not run my app.

Has anybody experienced (and possibly solved) similar problems?

very much
