Bis13 Asks For Password To Apply Changes Randomly

So I just got BIS13 up and running on my new laptop running Windows 8 (64) about a month ago, and I've been mostly pleased, except in the past few days it's started randomly asking me for my password to apply mystery changes I never asked for.


It would be nice to know what it's asking for, and why, and if this is normal.


Any relevant feedback would great.


On a side note: I can't edit my personal profile in the forum. I don't know if that's on purpose or not, so just throwing that out there.
