[PATCH] Openpgp-applet's output dialogs don't appear in window list or alt-tab and thus can be mistakenly left open
The issue seemed to be that MessageDialogs without a visible parent window don't behave correctly. I changed it to a regular GTK window and now they appear in alt-tab on my machine (Mint 19.3) and appear in the window list. It's very easy to leave one open without this patch potentially exposing sensitive data.
