I am currently tunneling though ssh as the raw X was a test only to see if it was a tunnel issue. > >> Testing with antivirus and firewall enabled/disabled did not affect >> the results.

Corporate Policy prevents it on several levels. However, my disable of the A/V-firewall packages was by going into the Windows Services applets and disabling the services there and via a couple registry hacks and then rebooting so the A/V and firewall pieces could not load to start with. They are as ruled out as I can make them currently. I will look into the possibility of a VM to test without them entirely and see if i can still reproduce the issue. > Also (not necessarily related to this particular problem), cygcheck reports > a surprising selection of *nix-like utilities in c:\windows\bin.

In theory, since they are later in the path in the cygwin environment, they should never be executed unless called by full path, but I do appreciate it being pointed out. I should have mentioned their existence on this machine to start with. > I doubt it's an X-server code issue.

The only (known) BLODA I have from that list is the McAfee A/V-firewall, which I can't remove, but I believe was completely disabled by the above described method. > My advice: check out the cygwin FAQ about BLODA, uninstall anything listed > there (or install a fresh VM image somewhere without those) and try again. > If it's still a problem, somebody more familiar with X than me will have to > take over... > > Ryan If I can get the authorization for a VM test without A/V, I will and the results will be posted here either way.
