Yep, you were right.

I found out that OM Weather has a memory leak in it. Time to let the developer know. I was thinking it was a certain program I installed, but I didn't know for sure which one, but I also didn't know applets were part of the hildon-desktop process. That helped me out a lot. This will help me out in the future for debugging memory leaks in other programs.

You're an asset to the community for helping out. Thanks again! ^_^
