[openbox] Openbox sometimes hangs, can be reproduced

[Donald Jenkins]

Hello, Dana. Thanks for your reply.
And if app will suddenly freeze, there will be freeze at all, without
any chance to escape? How I can avoid this?
I confirmed it on IceWM, so it not an openbox bug. Sorry for any inconvenience.
