Description Kumāra 2014-07-10 06:22:44 UTC 
Situation:

When I experience a system crash or power cut, there's a chance that I lose settings in registrymodifications.xcu. (A new file is created upon reload.)

This seems to happen when the file is being written, and the chances of it is greater when AutoSave is set more frequently.

It has happen to me a few times before. Now I have it backed up regularly, thus it can be restored. However, this can be very annoying for non-power users.

Request:

EITHER
Isolate the AutoSave from registrymodifications.xcu

OR (at least)
Have LO run AutoSave only if indeed changes have been made to the doc. (This shouldn't be difficult as LO already has the ability to detect changes since last save. The change of color in the Save icon indicates so.)
