Klaus (and others),
I did speak with Brian today, he will implement the "Horizontal Slider" in the version 4.0 release of Mach3. I spoke to Art as well, and you are right Klaus, Mach 3 does indeed Re-Implement the screen designer code. Art said to me that the Screen designer code is also repeated in Mach3 so it can use the objects of screen designers. So, even though we can make the external Scream4 Make Dog&Pony shows, it apprears the the internals have to run that same show........ Kinda of a bummer in a way. So, my hopes where dashed that we could work around it without having to do a Mach core change.
Scream4: I was having many troubles with Scream4, so Art had sent me the code to see if I could get things like the Menu items to work with Vista 32 and 64, as well a few other bugs like scroll wheel on the mouse. Unfortunatly, the Screen4 is largly based on the "Ultimate Tool Kit" which will only support XP. I did try and find and replace menu dialog items with thier Vista compatable objects. That was a NO-GO for sure. In the end it would have required a complete re-write of the screen designer to run with Vista, so I am very, very glad you have came along!!!
