Joplin running when Windows is put into sleep mode. Wake Windows. Click on Joplin icon on taskbar. Joplin window does not appear. Right click on taskbar icon, choose close window: Joplin does not close. Must kill in task manager and relaunch.
I have similar issues where Joplin becomes sluggish or unresponsive after my PC idles or sleeps for too long.
My system resources are nowhere near their limits when Joplin is like this, so I would rule out resource hogging or plugin causes in my case. Is this the case for you too?
I would expect that quitting Joplin before putting the PC to sleep prevents this issue. Not having to resort to that would be preferred.
