This is a known bug in xorg-server 1.7.5 and is apparently fixed in a recent patch. https://bugs.freedesktop.org/show_bug.cgi?id=25400 Xastir, a port in the comms tree, uses Motif and is now exhibiting this cursor-grabbing behavior. The Xastir CVS tree has a workaround that allows Xastir to work even with the broken xorg-server 1.7.5 version. Note that the change in X server has actually impacted all Motif programs, this issue is not isolated to Xastir. >How-To-Repeat: Update xorg-server to 1.7.5,1 (the version in ports as of 6 May 2010). Install Xastir. Start it. Right-click in the map window. The mouse cursor will switch to one that points right, and it will be confined to the bounds of the Xastir map window. The only way to get the desktop responsive again is to switch to a non-X virtual TTY and kill the Xastir process and the X server. >Fix: The work-around is simply the patch that was made in the Xastir source tree today. It should still work even in the release-version code that is currently used by the port. The patch from main.c revisions 1.792 to 1.793 is attached here as patch-src_main.c.txt A better "fix" would be to incorporate a patch to the xorg server that fixes the broken handling of passive grabs, since that will fix *all* motif-based programs, but apparently there is still some work to be done to get that patch right. See the discussion in the freedesktop.org site.
