Vista Home Premium
Ruby 1.8.6 p111 (one click)
windows-api 0.3.0
win32-api-1.4.2

Here's the actual message. It's the call at line 756 that's ultimately
causing the issue from what I can tell:

C:/Ruby/lib/ruby/gems/1.8/gems/windows-api-0.3.0/lib/windows/api.rb:484:
[BUG] Segmentation fault
ruby 1.8.6 (2007-09-24) [i386-mswin32]

Ideas?

Regards,

Dan

PS - In other news, I messed something up with windows-api and VC++ 9:
