Accidently created .mdc file instead .py - system still thinks its a .mdc

I have reindexed and exited and now am going to restart cursor - but this is not the first time I have had troubles renaming .mdc files, though previous I never changed the extension to somthing else …

I appreciate rules are very special case file handling fo cursor …

But the renaming problem can be problematical for logical naming freaks like me that like to changes things !

As the rule gets older its easier to deal with, but fresh creations are sticky
