Yes ... but not necessarily correct everywhere ... just in the code I tested ... mostly I was running Gorm as a test application. Also, I was testing on Windows-XP ... When I was trawling the net for info on windows transparency, I came across stuff saying that older (but quite recent) versions of windows didn't support it, so I suppose that it's possible that Windows 2000 doesn't ... in which case I guess we need to work out autoconf stuff to determine the windows version and enable/disable it accordingly. _______________________________________________ Discuss-gnustep mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnustep
