Mysterious Shortcut Behavior

I use the free version of EssentialPIM, which has a series of assigned keyboard shortcuts, of which I use only Ctrl+Shft+S and Ctrl-Shft-T. A while ago, needing to see the calendar, I used Ctrl-Shft-S, which as has been true for quite some time, brought up the calendar.

When I was done, I again pressed the shortcut, but nothing happened. The icon for the open program was on the task bar, so I tried it, which did nothing; therefore, used the icon to close the program, which I then reopened. When I did that, it stated that my two shortcuts, plus a few others, could not be registered as they were in use by other programs.

I tried Ctrl-Shft-S, which did not work, but despite the error message, I found that Ctrl-Shft-T brought up the module for creating a new task, as it should. I closed the programs that were open on the task bar, which did not allow Ctrl-Shft-S to work, so I rebooted.

As EssentialPIM loads upon reboot, I again tried Ctrl-Shft-S, which brought up the D:\Pictures folder instead of the calendar. Wondering how to change that, I did a search, which turned up more than one set of quite wrong instructions, so came here, did a search, found the tutorial. I don't know why I again tried the calendar shortcut before even reading the tutorial, and to my perplexity was confronted by the calendar, which has continued to work for at least three or more tries to open and close the calendar.

Any idea as to what might have caused this mysterious behavior? I certainly don't get the picture....

Not mentioned in that list is Microsoft Edge Web capture (new to most of us this year) which also uses Ctrl+Shift+S.

It sounds like another program that was running or else had been running used the same hotkey combination and grabbed it. If you can work out which program was running try cofiguring other hotkeys in the program's options.

See if you have any of these installed.

What does the Ctrl + Shift + S keyboard shortcut? ‒ defkey

You can ignore programs with non user configurable hotkeys.

From my original message, "I used Ctrl-Shft-S, which as has been true for quite some time, brought up the calendar." And, as also stated, and as I just tried it, it continues to work properly. And, again, I had used to open the calendar, and while it was open, it stopped working; I had not opened any other programs after opening the calendar, nor did I see any notifications to that effect, so if some other program did start, I have no idea what it might have been. For that matter, the only use I have for the keystrokes is for my calendar.

All very strange. (Well, I'm not strange, but that does apply to the other items...).

Never used that, and MS Edge was not open when the problem occurred.
