Developers do not look for reports on social media, so they will not see it and all it does is clutter up the feed.
yes, the start menu or application menu...
sometimes a hangup in a widget or other taskbar or desktop customization can freeze up the menu. right click on the taskbar, enter edit mode, and resize the taskbar height one up and back down to where it was. if that doesn't fix it maybe remove any widgets or other customizations.
✔This solved it. Thank you very much!
Good grief. I'm used to edit mode being the cause for everything fucking up and freezing, not fixing things.
