Usually if you saw it on the administrator page where you import it then it will work. Just preview a scrip to anyone and look at the bottom if the signature works it will be there. Some of the formats that are state specific, etc did not work the last time I talked with AC.
It is really amazing how just having something wired improves performance - I don't use any really new state of the art computers, but everything is wired and other than patients with huge imported files (when I go to imported to look) everything is fast. I even still have an old Pentium something with 256 mb ram and a 20 gig hard drive as well as windows 2000 and it runs fine with AC (I really keep it just so I can point out to people that some softare does not require brand new computers with all the bells and whistles to work).
