Read file names properly

[Griffit]

I named a file myProg and the second version myProg2. Rev thinks that I have two files with the same name.Tried my2Prog and got the same result.

[timlit]

it must be referring to the name of the main card, not the filename.
Just rename it, or refraining from opening both files at the same time.

Yep, the NAME of stack <> the filename!
