[comp.sys.mac.hypercard] How can I trap for double-click in HyperCard ?

IP60538@PORTLAND.Bitnet (Earl Christensen) (12/17/88)

Would like to get different response from single and double clicks in
the same place,useful for creating auto drawing graphs. If any one has
any ideas, please Email me direct, as USM is very anti-Mac, and we
sometimes don't get full versions of this news group (the caps people
here still think Mac is a toy)  Thanks in advance for any help offered.
