Hmmm...just the act of having the MM .NET DevExpress controls on your machine shouldn't affect any of your non-MM .NET projects at all. I wonder if the DevExpress installer might have had an ill effect on the MM .NET DevExpress project?

In any event, we will have the updated DevExpress controls out soon and you can try themn out.
