Today I get a message stating

"Istaria is already running from:
C:\Program Files (x86)\Istaria
To run multiple instances of Istaria, each instance of Istaria must be run from a separate folder."

I have been running multiple instances from the same folder for years, why the sudden change?

If this is a new requirement, is there a way to share the same prefs folder between instances so I don't have to maintain multiple copies of hotkeys and such. If you have more than two characters, this could get out of hand.
