Yeah, I get what he is after, but there is more than one way to skin a cat. Another would be to allow a remote desktop connection. Then no software of any kind is needed for the client other than the RDP app. Still more work on the client end but installing a canned app isn't that hard. Browser based apps can be work to get running on multiple browsers and keep running with browser updates. A friend is in that line of work and there is *soooooo* much work keeping all the different versions working. -- Rick
