Hi Stig,
sorry to hear that you're facing problems. Of course MIR is not supposed to act like that. :-) .... but GUI-related problems are a bit cumbersome to hunt down as they are so many system-specific variables in that respect.
I see that you're using several computers. Is there any remote desktop-application involved? Does the MIR Icon work with other instruments, on other VE Pro channels? Any chance to see some screenshost or the like?
BTW - I strongly suggest _not_ to use Vienna Instruments-specific Instrument Profiles for any other sound source (even if they carry a similar name, by incident). These Profiles are highly specific and will very likely cause undpredictable results when used with other input signals. There are so-called General Purpose-profiles which are meant to get used with generic signal sources.
Kind regards,
