Højde på nyt vindue.

Vha. nedenstående script åbner jeg et nyt vindue, og viser et billede.

Hvis jg anvender PopupBillede1, så passer højden inkl. de 15 pixel. Men hvis jeg anvender PopupBillede (som jeg selv sender højden til, så bliver højde hele skærmen.

Er der nogen der kan gennemskue problemet?
