Excessive Cache Use?

[cj100570]

I'm running the Genie Widget on my Droid and I've noticed that it seems to be using up quite a bit of my phones memory. Over the course of a few hours my Droid goes from having 175Mb of free space down to 54Mb. When I go into applications and have a look I always find that it's being taken up the Genie. When I clear it's cache all the memory comes back. Has anyone else noticed this and is there a way to have it cleared out automatically?
