[Xquartz-dev] 10.4.3/2.3.0-rc2 - stuck ctrl key

Hi, Just installed 10.5.3 and 2.3.0-rc2 and I've noticed that the control key gets "stuck" when using it to switch spaces with X11. E.g.: I have an xterm in space 1. I click on the one in space 1 to activate it, and use control+left arrow to switch to space 2, the control+right arrow to go back to space 1. Clicking on the xterm now brings up the xterm menu, as if I pressed control while clicking. Pressing the control key again seems to clear the stuck key. Cheers, Jamie
