I take it back, it worked for a short while and then one macro threw the error about “Invalid value for bounds” and now it is broken in Chrome again. Seems to still be working in Edge though.
Well now Edge has stopped working again after running macros with no issues. It failed with the same bounds error and now will not do anything.
Just found this Emergency! Cannot open UIVISION! - #10 by toku post and there is a reply stating that if you move Chrome/Edge from full screen into the corner then it opens properly, and it does. Not sure how this helps, as I need it mostly full screen, but it is something.
