Photoshop :: CS2 Registry Error

Cleaning ou tmy registry recently, I discovered that photoshop is leaving entries in the registry for every file I edit. These are "recent" file entires, but instead of deleting any more than ten, it is keeping them all!!! It does it every time you edit the file too. This means that I cleared out some 5000 registry entries that photoshop had failed to remove. Thing is that because they come under the type "file path problems", not all registry editors will even see them.
