running "mac" without arguments = endless cycle

[r0n]

I noticed when running a "mac" command without parameters (to be clear: only the "mac" command), results in an endless cycle of: "Warning (RT) in ... Launching macro from". Normally a user would not run it empty (no arguments).
I also tested this in a clean portable version of QM (the state in which QM is, immediately after a clean installation).
