Public bug reported:
When startting XView applications like cmdtool, the application starts
and reacts to keyboard input, but after the first mouse click inside the
window (not on the window title bar), X hangs. Switching to a text
console is still possible, and after killing the application, all is
fine again.
When I login via ssh to the ubuntu machine from a remote machine, there
is no problem. But when I log into that remote machine from the ubuntu
machine, X also hangs when I start cmdtool
I am using Ubuntu 9.04 (in VMware player, downloaded from vmplanet.net),
and xview-clients 3.2p1.4-23ubuntu2.
Below comes some strace output. I started the cmdtool, entered "12345"
and waited a little, te first part shows the bottom of this log. The
next part is from this point until after I clicked with the mouse into
the window.
