On mouse Up event not triggering the first time

this was the only other thread i could find with for what i could tell the same problem, but i tried setting focus and it didn’t do anything to help, and messed with some interaction of the interface the widgets in. only difference between that problem and mine from what i could tell is that mine doesnt fix itself if the previous click was on the widget, only if i double click and on the release of that does it fire
