Canon CR2 Codec Memory Leak

Running Vista, I have installed the Canon provided RAW codec for CR2 format. It allows you view those files natively.

I was browsing through a folder of pictures. I noticed that it got slower and slower as I went through the pages. Eventually, it gave me an out of memory error. I didn’t have anything else open. I brought up Task Manager and saw that I had memory left. I closed the picture viewer and just watched the memory get reclaimed in about 20 seconds. The total delta there is about 1.5 gig.
