First, Win Forms are just a preview currently in Mono, because they
aren't complete and rock-stable. But let's look at your problem.

Well looks like you are consuming all your memory/stack-space, because
you are calling Main recursively in the Form constructor.

DON'T DO THAT!!! Main is automatically called by the runtime, and it
normally calls the constructor for the main form, not the reverse. You
are just making it into infinite recursion... What truly can't be
infinite because at some point you consume too much resources (memory in
your case) and the program aborts.

Also it helps to read your code and the stack trace, to find what and
where the error is so probably you could figure out yourself what was

Hope it helps,
