From 8ae75f3ca723d4d7e449c18f1704147b229ac66c Mon Sep 17 00:00:00 2001 From: Lukas Fleischer Date: Wed, 28 Nov 2012 21:42:54 +0100 Subject: Ignore signals during command execution Disable signal handlers in wins_prepare_external() and reactivate them in wins_unprepare_external(). Before, it was possible that resizing the window during editor/pager mode resulted in the calcurse main screen appearing on top. Addresses BUG#9.
