SikuliX Stopped Working - running on secondary monitor

[D474designs]

I have been using SikuliX for a long time now; Recently I opened SikuliX, and it would not get passed the loading screen.

I have tried every Java SDK build, including 21, 22, 17, 11, and 8; I have redownloaded SikuliX 2.0.5, and 2.0.6.

I have never had a problem before.

The last time I opened it, it ran for a little, and stopped working after the first action. I was also getting the "mouse... blocked" error, which I had not been getting beforehand.

Any help would be appreciated!

I got it back up, and running, on JDK 22; SikuliX seems to have a problem when running ONLY on a secondary monitor, this problem seems to exacerbate when using applications in full screen, and changing the screen setup.

I will update if I find out more on the specific problem, the only thing I could extrapolate from logs, was, the monitor setup was causing a hang up:

After this point, SikuliX will not load any further, the loading screen stays up, and no further information is thrown.

These two lines might be the only clue as to the issue I was able to resolve, by changing my screen configuration via Windows' Project Mode:
[SXLOG 8.922] [error] Region(4385,523,510,344) outside any screen - actions might not work
Exception in thread "main" java.lang.NullPointerException: Cannot invoke "org.sikuli.script.support.IScreen.capture()" because "_screen" is null

Another nuance I noticed with the Region error, the screen positioning affects the grid which SIkuli X uses to dictate cursor location. After switching primary monitors, a resolution change, and moving the screens on their virtual plane, Sikuli X stopped loading completely with the, "...outside any screen..." error as the culprit. I was able to reverse the screen positions to offset the error.

I recommend a variable system which begins at the center median, and expands it's size from said point, until all screens are encompassed. This system would be similar to the existing system, which centers around a primary screen.

The edge cases being the change in resolutions, the change in screen positions on their virtual plane, and changing primary screens; The problem carried over to other versions of Sikuli X, indicating this was in fact a hard coded error.

The new system would correct the cursor being detected "outside," of range; Thank you for you work RaiMan!
