Hi
I've done some more testing... I can confirm that my application doesn't work (i.e. I get the same problem) with: Cygwin/X, VcXsrv and MobaXterm (tried all combinations of settings) However it does work with Xming.. What is in Xming that isn't in the others or is it a setting/command line parameter I need to use? Tried it on 2 different machines (Windows Vista 32 bit and Windows 7 64 bit) and the same problem appears on both. Incidentally both machines are running ATI Radeon cards. I want to use Cygwin since I'd like to redistribute the binary. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/
