Where is the Visual Studio layout saved?

I am having problems with VS2008 moving the windows around and losing tabs when I close it and open again, or when I go from coding to debugging and back. (Yes, I know that it is supposed to save different layouts for coding and debugging). I have tried exporting my settings, but it informs me helpfully that

"Your settings were exported, but there were some errors. Error 1: Some command bar settings were not exported correctly due to an internal error."

Importing them again gives a similar error, and doesn't solve the problem. Does anyone know where VS saves the layout info? Or how to reinitialise the layout, without changing all my other settings? Thanks!

• This is what you're after:

  Tools > Import & export settings

  You will need to make it work though. Maybe manually saving it from My Documents\Visual Studio 2008\Settings

  Joel in Gö : this is what I tried that gave me the error message, and did not solve the problem.
• • Export your current settings. Don't choose to export the layout settings.
  • Reset IDE settings to your favorite
  • Import your exported settings

• You might want to try Window > Reset Window Layout. This will reset the windows the way they were configured the last time you imported a layout.

  Joel in Gö : Thanks, tried it - no difference :(

• It sounds like you might have a permissions problem trying to export the files.

  Another possibility that's a little less likely is that your *.suo files are being versioned, and so when you update your projects your layout for that project is updated as well.

• Some of the layout information is stored in the registry for the current user.

  HKCU:\Software\Microsoft\VisualStudio\9.0

  If you're really having a lot of problems you can take the desparate step of deleting or renaming this key. Personally, I would rename it, start VS and see if that fixed my import export settings problem.
