Stop popup " do you wish to convert existing data"

[studiopeg]

I cannot stand that Freehand 10 gives me a popup box asking "do you wish to
convert the existing date on the clipboard before existing?" everytime I exit
Freehand if I've copied and pasted something, anything.

Cannot find out how to turn this off. Checked the preference tabs, nothing.
Ran a Google search on the phrase, nothing.

Anyone know how to stop this freaking annoying popup dialogue box from
happening anytime I exit Freehand with anything on the clipboard (other than to
take the extra step of clearing the clipboard...)?

Thanks.
