Really silly problem here.
In Visual Studio 2010, the text cursor has changed from the blinking line, to a blinking grey box around the characters. When I type overwrites the text in front of it.
I'm not sure how to get this off? It's like what happens when you press the insert key in microsoft word and overwrite mode gets turned on.
I'm working on a mac with a windows virtual machine so when I hit insert it's just a shortcut key for Parallels (the Virtual Machine program I'm running).
Would appreciate any help!!
If pressing the Insert key doesn't work, try doubleclicking the INS/OVR label in the lower right corner of Visual Studio.
