This is the "First Draft' if you will of a routine to rearrange the tab order.
The dialog box must be in the ACAD path.
Highlight a tab in the pick list then use the Up/Down buttons to move it.
Continue with other picks until you have the order you want the select the
Finished button.
I only have a few hours into it so there is a lot of cleanup to do yet but
I thought I would get some feed back before I go for round 2.
So if you don't mind alpha testing
have a go with it.
I did limited testing in ACAD2000 only.
Code updated, see later message.
