It's the XMP sidecar setting for "other programs to view LR changes". Picasa was constantly updating the thumbnails as LR redrew = sloooowww and annoying glitch.
The good: I've found it and can switch it off (you have no idea what a relief it is to edit without that!)
The bad: I'm still stuck with only xmp's in my catalog instead of next to the files.
Hmmmm....
Not true. You can select the photos and press command-S (control-S on a PC) and it will manually write the XMP metadata out. That way you can do it on your schedule.
I really consider the XMP files to be a "backup" to what's actually stored in the catalog. I don't tend to use other tools that are reading from the RAW files directly. I would ALWAYS manage them through Lightroom.
