I have Resharper 4 installed into Visual Studio 2008. On 64-bit the CTRL-F functionality crashes the application, which has driving me nuts. My colleague Anand posted a solution to our company Intranet, so I stole his post for my blog for future reference.
Thanks Anand ;)
“Visual Studio might crash when using the Find feature on a 64 bit system. This msdn article explains the issue. KB947841 I uncovered this problem after installing resharper on a 64-bit system, however, it is not related to resharper. Installing this add-in simply uncovers this bug in visual studio. You need to request this hotfix ”
