Guys,
The Cache problem is ACTUALLY an Adobe problem - not a WebAssist problem. In fact, the cache issue is well known at Adobe and I am told it will get fixed in Dreamweaver CS5. It is Dreamweaver that is not operating to the specifications that it is supposed to.
But not everyone has the problem so no need to get upset... there is a pretty thorough support effort here that correct any problems, though, should they arise.
