multiple monitors - sometimes print screen key does nothing

I am running Windows 10, build 15063, with Hypersnap version 8.14.00 (64-bit).
 
I currently have 2 monitors on my system.  The primary monitor is on the right, and the secondary monitor is on the left, so it has a negative X co-ordinate.
 
Sometimes the print-screen button on my keyboard does nothing, Hypersnap does not respond at all.  There is no sign that Hypersnap has even registered a key press.  I think the dual monitors are a factor, but I have not been able to pin down the pattern yet.  Other times print-screen works correctly, and captures the entire active monitor, which is the monitor the mouse pointer is currently on.
 
Are there any known bugs like this?  Where should I start looking for clues, and what information will help to explain what is happening?

    What settings exactly do you have selected on "Screen Capture Hot Keys" screen, when you click Capture ribbon tab - "Hot Keys" button? Specifically, does the "Enable Hot Keys" field have a check-mark in it, and what _exactly_ is selected in the "Print Screen Key Handling" field?

    Enable Hot Keys = On
    I keep this On, at all times, even though I have customised the hotkeys themselves, to avoid conflicts with other programs.
     
    Print Screen Key Handling = Capture Full Screen
     
    which, on my system, captures the "current" monitor, and only the current monitor.  In Windows display settings, it is currently listing 2 monitors, as separate monitors, which is correct.  When I finish moving house I will be back to 3 physical monitors.
     
    When the problem is happening I found bringing HyperSnap to the front, going to the Capture tab, and pressing the "Full Screen" button worked correctly, even though pressing the PrintScreen keyboard button had no effect.
     
    Once the PrintScreen button is working again, it does not seem to matter which screen I have HyperSnap on.  The current monitor is always the one with the cursor, even if the current program (window) with keyboard focus is on the other monitor.
     
    One other setting change I have made is to set:
     
    Capture settings -> Capture -> Delay time before the capture = 0 milliseconds
     
    I have been using HyperSnap for years, and have it set to load on windows startup, and also to load minimised.  I have only noticed this problem with screen captures not being triggered in the last few weeks, which suggests it is a recent problem.  Unfortunately vague.
     
    From what I have noticed, when I first turn on the computer HyperSnap is loaded, but is not responding to keyboard shortcuts.  Once I do "something", perhaps related to moving HyperSnap between monitors, it starts responding normally again.  I have only just discovered this though, I actually thought HyperSnap was not responding to any keyboard shortcuts at all, regardless.  Which was odd, since I could set a new shortcut in the hotkeys settings, and they were picked up and recorded by the dialog.

    It could be that another program is intercepting PrintScreen key when it's not working in HyperSnap. One user - or was it you? Can't tell with Forum aliases - wrote to me in email today, that he figured out Print Screen problem, in his case it was caused by Dropbox app, specifically by the setting to enable the option "Share screenshots using Dropbox"

    Nope, not me.  I had no idea the dropbox app had a setting like that...  Just found it, and the setting is already turned off.
     
    It makes sense that some other program is capturing the print screen event, but from memory, when this is happening, none of my mapped keyboard shortcuts for HyperSnap are working.  I need to re-check this.  I know I am not fixing the problem by closing and re-opening HyperSnap, or closing any other running programs.
     
    Is there an easy way to see which program is currently listening for the Print Screen key?

    There is no way that I know of - Microsoft in its infinite wisdom, failed to provide such information to other programs or users.

    No surprise there, it was a bit of a long shot.  Sometimes when trying to set up keyboard shortcuts in programs, I am told that a given keyboard shortcut cannot be registered, since someone else is already listening for it.  That does not tell me where the conflict is coming from, but at least I know there is one, to go looking for.
     
    So I was wondering if something similar existed for the print screen key.
     
    I will just have to keep an eye on this.  For the last couple of days, no signs at all of the problem, typical.  I finally pinned down enough of a pattern to report it, and then it goes away.  I will keep an eye out for this, and see if it comes back again soon.
