Had a problem yesterday. Here are the notes that I took as I was trying to resolve the problem. Hat's off to the sensible person who decided that automatically backing up the site is a good thing:

Internal program erro:r 1+92.k.sy.up

Showed after the export of a PDF. Could not escape: Program would not close using the x at the trcorner or the task manager.

After some minutes the program recover to the extent that I could "Save as" under another file name.

After that I was able to shut down the program.

Attempting to restart it showed the error: Failed to read XAR file (Failed to read record 659 68) At this point there was a blank white window titled [Mobile]

Could load neither the pre error nor post error file. Will need to try backup.

Could not load latest Backup. Had to go back to the previous one.

After that all was well.

Please could someone pass this on to the relevant authority and let me know what the relevant authority is so that I don't have to clutter up the forum with this sort of stuff.
