I have noticed that if screenshot captor does not exit cleanly (like when it was hanging earlier after too many automatic captures), that it did not save the settings.  The saving of settings maybe only happens on exit?

So if your reboot/restart isn't shutting down screenshot captor first, and you hadn't previously exited cleanly after changing settings, that might be what is going on.

I found another issue with automatic screenshotter.  It seems that there is something wrong with the cleanup/delete of old screenshots.  I had it set to "0" for number of screenshots to keep, 500mb for disk space, and 500 for days to keep.  It was automatically deleting screenshots that were about 17 hours old... there were about 1000 screenshots in that time.  I don't remember if 1000 was the original default for number of screenshots to keep before I set it to 0, but it might have been.

I have now changed the configuration to "0" for all three settings, and I restarted.  Will post back here if the behavior changes at all.

beta version is installed and running.  GDI handles currently at 198.  Will let you know how it goes.  Thanks for the quick turnaround on this.
