Panasonic Lumix LX3 Annoyance

The LX3 is in my possession for a couple of weeks, and last weekend I noticed something annoying. When I imported the photos in Adobe Lightroom, some of the photos were imported as RAW, and some as JPG.

By default I set my cameras on RAW (if they support it). When I purchased the LX3 there was no RAW importer for Lightroom or Photoshop, so I shot in RAW+JPG. This way I could see the photos and could work with the RAW files when a proper RAW converter (Adobe Camera RAW) cae along.

I checked the format settings and these were set at RAW, so where did those JPG's came from?
After some searching I found that the iA mode of the camera (intelligent Auto) decides which image quality setting to use. Something I didn't find in the manual (or I read over it).

Anyway, it's annoying as hell.
