Hi all, I was trying again (unsuccessfully) to get a complete flight in with the PMDG737NGX. This time, KDEN-KDFW. In cruise, about 600 miles from DFW, the sim apparently froze. No mouse clicks, no change-of-view would occur. The speed and altitude info vanished from the both CDUs. There was no data in PROGRESS, and all the other usual CDU places. The autopilot would not shut off, the A/T would not shut off. Setting a heading in the MCP and hitting "HDG SLT" had no effect. The a/c just kept going on the course when everything froze. The ND and PFD did not update. This is the first time I didn't get a CTD, though. I could not re-load the flight (all screens blank) although the a/c did keep flying on the same course. (I've never yet been able to load a saved flight, or panel state, or both and have the displays appear). I obviously have zero luck with this a/c (no completed flights, all CTD or ending oddly, as described here). It figures that after waiting so long I'd be in the 0.5% that have trouble. So it goes. Any suggestions are welcome! dan "lensman" davison"
