RDP displays are blank
- Call up RDP Display as an overlap
RDP Displays come up blank. Most frequently this has been reported for LOOPFCM and Diagnostic's, but it could be any RDP Display.
The problem is 2 tasks on the RTAB are out of synch, and they no longer communicate properly. This has the effect of impairing a DPM Channel.The problem has been around for 2 years (?), dating back to OS1.4. No one is sure exactly when it first occurred, so we can't answer the 'What Changed?' question. The MTOS code involved has not changed in years, so the hunch is that the problem originates in the UNIX RDP code.
The work-around is to call up an RDP Display as an overlap, and 'nail' & iconize it. This ties up the 'impaired' channel, so the subsequent RDP Display invocation will go to the next channel, which is hopefully good. The same thing can happen to each subsequent channel. The RTAB needs to be restarted to truely correct the problem.
