Sorry, I have 4.60a for FSUIPC. I did not change the time on the the report. I have been flying only PMDG aircraft, latest is the MD11. But this started happening about a month ago and I just attributed it to the version of Flightsim Commander and that I had not updated that for a long time. Lately, I have been trying something different. I was watching web videos while I was flying, but have stopped doing that. It seems to me that if I only run FS Flight Tracker, FSC, Outlook and firefox (no farmville or any other game that requires lots of pc time...lol) I have not encountered the delays 'as much'...since changing that behavior, I have had only one instance of pausing and one hard crash of the FS. Before this, I usually would expect at the very least a hard crash of FS or the pausing of my flight in FSC...or both.
