Problem with uPerform Recording of ARIS Express

I discovered that I can't use uPerform to record activities in ARIS Express. I wanted to create a uPerform BPP on how to navigate through ARIS Express and do some basic model building, but once I start recording in uPerform, ARIS Express freezes, and I can't access the menu options, or work with the symbols, etc. Is there a setting in ARIS Express that can be adjusted to allow recording of activity within the application? Thanks much.
