However, during the past four trips I've experienced a problem with the main mapping window freezing and completely blanking out - requiring me to reboot in-flight with all the distractions that involves. Only the map window develops a fault; the Enroute Features window and the ETA/Altitude data etc is not blanked out. Indeed when viewed later the flight log shows the GPS tracking continued in the background.

If no one else has experienced this issue then I suppose it might indicate a fault with the PDA, even though it is dedicated to SD and hasn't had any other software added since SD was originally installed. Any suggestions would be welcomed.

I was beginning to think it was just me! One thing I have discovered since I wrote the post is that my software variations were not absolutely up to date: SD plan was 1.4.4 but my PDA was still on 1.4.2.

It would be interesting to know if you have both on 1.4.4. If so, my hope that this might fix the problem could be dashed. I had the same thoughts about my PDA capacity and the increasingly sophisticated software, but then I'd expect more people to have had this issue. They can't all be using the latest gadgets.

Anyone else out there hit the freezing screen issue?
