Visual Studio 2010 no longer showing DataTips during debug

Once upon a time, I could hover over any variable while debugging and stopped at a break-point, and would be able to get that variable's properties and values. I recently discovered this functionality is called a DataTip.

About a month ago, I lost this ability. Now, when I hover over a variable, nothing happens. I never knew how much I loved this feature until I lost it.

Can anyone tell me how I can re-enable DataTips?

I've been through the Debug menus but nothing jumps out at me and yel开发者_Python百科ls "HERE. This is what you are looking for!" The internets haven't been fruitful either.

As a side note, the only change that I can remember that occurred around the time that I lost DataTips was connecting to our newly set up TFS for the first time. I don't see how this would affect the DataTips, but stranger things have happened.

I figured it out! Turns out there was one other change I had recently made to VS that was responsible.

Not long ago, co-worker had sent me a link about Debugger Canvas. I thought it looked pretty cool so I gave it a shot. After a while I decided it was not for me but left it sitting around in case I found I had a use for it. Naturally, I completely forgot I had it installed to VS.

Long story short, I stumbled onto a forum post titled Debugger Canvas broke my Data Tips. Thinking, "why not?", I uninstalled Debugger Canvas via Tools > Extension Manager and viola! My DataTips are back.

This isn't quite a fix if you are actively using Debugger Canvas (until they, themselves fix the issue), but it is certainly a fix for me.

After much searching I discovered why I was having an issue with data tips not showing. To my knowledge no one has yet mentioned it in all the blogs I scoured. It wasn't the VS SP1, Debugger Canvas or any other software installation. As I was about to start systematically uninstalling a bunch of stuff, I realized that my current mouse problems might be contributing to this. I had a wireless mouse that was acting up. It wouldn't scroll, or activate within a window or allow me to click on the task bar among other things. So, I spent $20 bucks an bought a wired Microsoft mouse, the cheapest they had. Well, wouldn't you know my data tips appeared. Keep in mind I uninstalled/reinstalled my mouse driver already.
