No, but if it's any compensation, cvs has been broken under Cygwin since, well, I've tracked it back to around 7th Jul. For me it started when I downloaded a clean copy. Norman Vine's version is exiting as soon as the load sequence finishes, mine and a machine AJ is testing on hangs at the same point. At the moment the problem seems to be in Simgear, possibly in Harald's new GL stuff, but that's a very tentative diagnosis. Right now I can't see anything obviously wrong, and am really at a loss as to what to do next. The last known good seems to be 7th Jul - you might like to roll cvs (FG and SG) back to that point and see what happens. I'd be interested to compare notes Vivian _______________________________________________ Flightgear-devel mailing list [email protected] http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
