Subject: gui: Avoid bad terminal state with xterm.
X-Git-Tag: v0.5.6~23^2~6
X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=be46d3b63c855fe63ecc6feb7c4a2d3edab92307;hp=ec7552f87eb959b007bd0ed3642e5ccc2faa4d39

gui: Avoid bad terminal state with xterm.

If para_gui is signalled in external mode, and the running program
has set the mouse mask to receive mouse events, mouse buttons
(copy and paste) might not work after para_gui exits. This has
been observed at least with xterm and aumix as the external program.

Setting an all-one mask seems to cure the problem.
