I get the following JScript Debugger error when I click on the Start Debugging button in the Script tab of the Developer Tools (F12) window:
Unable to attach to the process. Another debugger might be attached to the process.
- Closing all browser windows and launching ie again has no effect.
- Ending the process tree in Windows Task Manager and starting a new iexplore task has no effect.
- Hitting Shift-F5 when in the Developer Tools window has no effect.
- Rebooting the entire machine reveals how desperate I am and has no effect.
- Searching in Regedit's [HKEY_LOCAL_MACHINE\SOFTWARE] branch for "JITDebug" just reveals I don't know what the hell I'm looking for.
