问题
I think I mistakenly hit some unknown key sequence in Visual Studio. Now, my mouse is this horrible/useless square box in the GUI instead of the default arrow.
Here is a video: https://www.youtube.com/watch?v=Qo1oqg2Wl5k
Does anyone know how to change that back?
The closest issue I found related to this was szalski's solution. It did not solve my issue, though. It just turned the box black.
Is there a way to embed the video instead of leaving a hard link?
Update:
The Right-Click the controls and resetting the toolbox did NOT fix this oddity.
I wished this guy had posted his solution:
Square mouse pointer in Visual Studio 2008 designer
RESOLUTION
Hans' recommendation fixed this.
