>I have a container that's very wide about 7000 pixels. I have the scrollbar prop set to true on the form but it doesn't scroll to the end of the container. Is this a bug or a limit on the scrollbars

There's a limit on the size of scrollable form which is about double of the desktop resolution. See mskb #Q216985 BUG: Scrollbars Disappear if Objects Placed Past Certain Length for details. The limit has been increased in VFP9.
