Call methods to closed window

[kim at martel.com.au]

Thank you Reg & Kelly

I just added $cando as suggested by Reg

   Do iCallBack.$setAttachments.$cando() Returns #F

And if window closed it ignores line and continues
Regards
Kim

Hi Kim,

You could try   If  iCallBack.$setAttachments.$cando()   which may or may
not work in that context, i guess.

Kind regards,
