Customer on Sage 100c Advanced 2016.3 - they are using FRX and one user reports that he cannot go into both Sage 100c AND FRX without getting the message "" 1 User Limit Exceeded"".
I cannot recall there being a limit to running FRx and Sage 100 at the same time - but maybe there is/was and I just never ran into it.
He says when he exits FRx he can then get into Sage 100 on his desktop.
He is logging in from his regular desktop (ie - not TS or Citrix).
