A week or go I did a system restore.
Since that time, a reboot causes several strange things to happen.
For example. I reboot and Thunderbird remembers some but not all email addresses. I reboot again and all email addresses are there.
I reboot and my PHP IDE forgets everything, including the fact that it has been activated. One more boot and things return to normal.
Obviously the registry is loading different files at different times. I'm just curious if anyone has experienced anything similar. I'm ready to re-install but thought I check here first.
