WindowMaker modifies application files even if I don't do anything

Hi everyone!

I'm very new to InTouch, I've noticed that whenever I open an application with WindowMaker it modifies a lot of the application files right away, even before any modification on my part... For example, the files under Web\DisplayFiles.
Is this normal? Is there a way to disable this behaviour, for example "wait until I save the project before touching anything"?

(I'd like to version control my application using Mercurial or Subversion, but this makes it somewhat harder)

Thanks for your time!
