Upgraded to V6.0.9 over the weekend. Today everything ran smoothly except the rx writer. The Star tsp rx printer prints the prescriptions such that the wording is oddly placed. Only the brother and the 8 year old HP 1022 print correctly, the 3 HP 3640's print prescriptions that are the size of a large postage stamp. Called AC support but no return response today, they must be busy with the move. All my machines are dual core with win 7 professional. The rx writer is a tad slow but the delay is tolerable. Documenting "meaningful use" is time consuming esp when the patient presents with a minor complaint. Office staff agrees that overall it's pretty cool.
