Our proprietary Telephony application is being disrupted when Lotus Notes is running in the background. Specifically, the comport used for our application is being slowed considerably or data is lost completely. Also, once our application is brought to the foreground keystrokes are delayed as much as a few seconds, then released all at the same time. So as we attempt to do something in our application, those actions are piled up, then released. Out application is a telephony product so it it interferes with call processing. We don't experience this problem with any other applications, just Notes.
