G'Day again,
So we really do not know when the error occurs - it is "just there" when you turn on the display in the morning.
And given you need to exit and restart Logic, it is probably bad data being fed to Logic at some point.
I think Dennis uses .Net and DirectX for the map, which get updated by Microsoft, and Dennis may have made changes to the Map code for .60. Either one may "run out of memory". When the backup runs during the night, at some point, it will have to take exclusive use of files to actually perform the backup. It may simply be the ""Russian roulette" of that process.
Clearly when you turn on the display, you want to see spots from the last hour or so. If it is a problem with Logic, to help Dennis find it, I suggest a couple of things ... waiting for the error to occur in between.
Yes, I know. Its a real pain. But, without some pointers to where the problem is occurring, finding a solution can be impossible.
Terminate and reload Logic, just before you turn off the display in the evening. Keep doing that util the problme occurs.
Simplify the map - before you turn off the display in the evening, turn OFF the Sun terminator and/or Lat,lon lines. If the problem occurs turn them back on and go to the next step.
Don't update the Spot log - again before you shut down for the evening, close DXSummit. If the problem occurs turn DX Summit back on.
Or ... turn off the spot log and just let the map run.
I hesitate to say stop running the backup for a while. But, you might like to "exclude Logic" from the backup process to see if the backup is causing the problem. I am assuming one can do that in 8.1. One certainly can in Win7.
Finally one can "down grade" by running the .59 update over the top of Logic. Does the problem still occur - then it must be something that has changed in .Net or Windows - the libraries Dennis is using. If the problem occurs, reload .60.
I am sure Dennis will appreciate the formation you gather to help in finding the problem.
