Problem: Debug is not working for VS 2005 with IE8
- Go to Start
- Select Run
- Enter RegEdit (this opens Registry Editor Window)
- Go Thru HKEY_LOCALMACHINE\SOFTWARE\Microsoft\Internet Explorer\Main
- Check for the key TabProcGrowth, if you haven't find add new DWORD with the name TabProcGrowth
- Set the value to 0
Reason: This problem is because of opening of multiple instances in IE8 browser. IE8 has a feature called "Loosely-Coupled Internet Explorer (LCIE)", which isolates the Internet Explorer frame and its tabs into separate processes. Because of this seperate process between IE frame and Tabs, Older versions of VS debuggers are getting confused to connect to the exact process.
Hope this will fix your problem.
