A new version, with a temporary bug fix, has been released.
Issues that temporarily fixed:
OSError - screen grab failed
#1
This issue has been fixed by covering the code section with try expect function; thus this issue is still there, but it will not stop the entire function of the program. Until now, I figure out that the screengrab issue isn't somewhat that I can fix: maybe that is an issue that related sleeping mode, screen saver, or kernel. However, if you have a solution for this or even better idea, please feel free to contact me!
Thank you,
