VS2010 - The application cannot start

Today I came to know one more Tip on VS2010 IDE
I am working on VS2010 and trying to perform some operations, code fast all of sudden I got black screen saying that
"The application cannot start".


Immediately I ran devenv/ resetsettings. But this didn't work.
I have VS2005 and VS 2010 installed side by side in my system.
Thanks to Visual Studio blog for the solution.

Cause
Since I have two IDEs running side by side, this issue might be due to importing a non-true Type font from of Visual Studio 2005.

Solution
go to command prompt and run "devenv /resetuserdata".
This worked for me in Beta2.
Microsoft acknowledges that this bug has been fixed in RTM

VS2010 Tip - JavaScript IntelliSense to work

Fortunately today JavaScript IntelliSense or jQuery IntelliSense in VS2010 doesn’t work in my IDE while it was working fine yesterday. Thanks for this situation. I came to know solution for this from my fellow MVP Rick for the workaround. The tip is very easy going to tools-> Export/Import Settings->select radio button reset settings. So resetting IDE works in many situations like struck in something or some IntelliSense don’t work.
