Recently, PL/SQL Developer has started redisplaying dialog boxes that were closed. Once reopened, they can't be closed - you can minimize them, but the okay, cancel, and upper-right 'x' buttons do nothing. Examples are the Crash Recovery window that is displayed at startup; multiple Template Wizard dialogs; and the Find & Replace dialog window. To get rid of them permanently, I have to kill PL/SQL Dev in task manager and re-open. The dialogs will appear and close correctly for a little while, but then for no reason I can determine, all of the dialogs that have been closed up to that point are suddenly redisplayed and cannot be closed again.

This is unrelated to any PL/SQL Developer upgrade (11.0.6 was released in April 2016), and there have been no Windows updates since 17May2018 (corporate laptop with an intranet update server - most users have moved to Windows 10)... I'm not sure when the issue first started, but I don't believe it is related to these updates. I have installed other software that may have included newer versions of common controls.

I have a screenshot, but don't see any way to attach it to this thread :(

Any idea why this is happening?
 
I'm not sure what could be causing this. Can you try the same with the trial version of the current 13.0.4 version?
 
Will that version co-exist with 11.0.6? As much as I would prefer to keep up with the current versions, I haven't been able to justify the cost; I can't upgrade if 11.0.6 isn't accessible when the trial is over (upgrades have made significant changes to ini/prefs files in the past... best-case, I'd be concerned about backwards compatibility trying to downgrade after the trial is over).
 
It also happens on v13. I took a screenshot of both PL/SQL Developers and their re-displayed windows side-by-side... if there's somewhere I can email it, I will.
