Certain part of my monitor is un-clickable. Kinda

[Msuni]

So i am having a problem with my right monitor (i have 3) at times i am unable to click anything on it in the bottom left hand corner. For example i can't change the volume or pause a YouTube video (while in fullscreen) i can hover my mouse on it but clicking only bring up the windows taskbar. This is occasionally the same for the taskbar in the same location as the pause/volume on a fullscreen YouTube video, however most of the time they are clickable. It's hard to explain but I hope that someone can understand what I mean lol Any suggestions/help is much appreciated.

I haven't tried that no, but I wouldn't of thought it would work because my other two monitors are perfectly fine. It's just the one monitor in the bottom left corner that doesn't work 100%
