I tested with and without the -resize option (I believe I read in the archives that -resize was unintentionally always in effect in the version with the bug). I haven't had a chance to try the new 1.9 build yet. I did encounter a strange crash the first time I ran the snapshot build. I was already running an Xming server, and the Cygwin server started without any issue but crashed as soon as I started a client. The backtrace made little sense to me -- it contained only two frames, the top being the GetDC API, and below that an unknown frame. Perhaps any unknown frame can give incorrect results below it, and obscure the true call stack? Unfortunately even the source of the unknown frame was missing (if I recall correctly), so there was no easy way to determine what additional debug information might be needed. Is it possible that the Windows Xorg port (which I take it is the basis for both Xming and Cygwin/X) does not support or properly handle running multiple instances concurrently? Whatever the case, the immediate problem does seem to have been resolved.
