Thanks for the detailed feedback Mr Happy. It seems you are a "bleeding edge" kind of guy with online storage.

Also thanks to the others that replied, everybody's input is of genuine use. I have some ideas for an application, more than likely freeware, and trying to get a feel for how it is used, and how to go about presenting it to a potential user. The user interface is always something that needs extensive attention, and I'm just trying to make sure that I present it in a way that is going to be intuitive to its key audience.
