Not necessarily. If I drag the selection box to include both boxes, I do want both of them. What confuses the users is selecting only the smaller box and ending up with both of them. In this case, yes, I'd want the last one in the list, but I can't programmatically determine what the user selected versus which elements the box actually intersects.
I hope this makes sense; pictures would be helpful if they could be posted.

(If not, you could sort it.) What you want is the last element from the list, right? -- J. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
