I've no idea, being a vimmer myself.
However, here's the first steps to troubleshoot this (and we'd probably
better take this off-line too).
build setup in your local sandbox. Then to invoke setup under the
debugger run
$ gdb -nw ./setup.exe
to invoke a windowless gdb. I find this much better for debugging GUI
apps than the GUI debugger, but that's just me :}.
I strongly suspect that the fault is being caused by my saving and
restoring the GDI clip region.
so.. msdn is your entry point to the calls I'm used -
<http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gdi/cl
ipping_4q0e.asp>
You might try
inserting a breakpoint at PickPackageLine::paint which is where the main
clipping manipulation goes on and then skipping the SelectClipRgn calls.
(Or just #ifdef that out).
Have a fiddle, and get back to me.
On second thoughts, MSDN just glared at me, I need a little bit of
OS-specific code that may (or may not) solve the problem. I'll try a new
snapshot with the appropriate code in 'sight-unseen' and if that
helps....
