Unable to dock extensions

I am unable to dock extensions… It was working just fine, but the other day it decided to not let me dock extensions. Ive tried a reinstall AND even reinstalled my OS in a last ditch effort on fixing this issue. Any ideas whats going on here? All it will allow me to do is ‘double click’ the extension and it will dock it on the top docking bar, but will not dock on the left or bottom bars. Thanks in advance for any help/advice!

I think that you actually mean toolbars ?

Yes, it is a known issue caused by a Windows system setting. See:
