Help with screen viewing

[AbsoluteVoice4u]

While presently using Calsnap to choose and enter a date in a filed, I'm looking for the avenue (script perhaps) to have the calendar pop up ON top of my layout page and NOT as a seperate page in itself. When I access the Calsnap, it pops up in a brand new window, taking up the entire screen. I'm sure there is a way to control the way the calendar appears but having difficulty. My need is for the layout page to remain on screen with the calendar pop-up showing somewhere on that layout. Your suggestion/solution would be greatly appreciated.

my CalSnap is a separate page to my database, but only appears in the top left hand corner as a box the size of the month...

could it be something as simple as clicking the box at the top right (where the minimise & close bits are)
