Description

Client system : Windows 2000 service pack 4 with all updates as of 2006.08.14 Linux server is SuSE Linux Pro 10.0 (fully patched)

Basic symptoms after logging in over XDCMP as any normal user: everything fine until I press a key, then longish (about a second) pauses on both mouse and key input. No CPU usage spikes on either server or client machine, so it appears that something is waiting for an event (that it shouldn't be) and timing out.

No problems with the previous release 6.8.2 version of Cygwin/X.

Colin Harrison <colin dot harrison at virgin dot net> reported that this patch fixed the delays, but stopped key repeat working:
