IMFD IMFD on external MFD?

[dundun92]

Last few times ive tried it straight up crashes Orbiter. Is it supposed to be like this, and if so is there any particular reason why it doesnt work on external MFDs?

IIRC, the only thing not working in IMFD (when opened on ExtMFDs) is the memory variable sharing, aka slaving one MFD to the other one.
