Prevent Visual Studio 2008 From Re- Autogenerating "My Project" Folder?

I am trying to rid my team's Visual Studio projects of "My Project" folders. None of my team is using custom settings or anything that would need to be stored in the "My Project" folder for any of our projects.

I have edited our .vbproj files with a text editor to remove any reference to "My Project", deleted "My Project" from disk, and ensured that no one has checked "My Project" or any of its files into version control. But when any of these projects is compiled, Visual Studio insists on autogenerating "My Project", re-creating the folder (just the folder, without any files inside) on disk and inserting a reference to that folder into the project.

(To clarify, when I say "a reference to that folder into the project", I mean that the .vbproj file contains the following text:

<ItemGroup>
<Folder Include="My Project" />
</ItemGroup>

and that text will not die no matter how many times I kill it.)I suspect that the chain of events is that VS modifies the project to include the reference to the folder; then after the project is compiled the folder is generated because it is referenced. How then can I prevent Visual Studio from modifying project files to refer to this infernal folder?
