Safari: Can't Find Variable: window, Date (Using Nested Framesets)


I'm using a frameset with a hidden frame to be able to hold onto my objects as the content of the window changes. If the bottom frame is itself a frameset and I load a new page in that bottom frame, I get the following Javascript console error when referring to "window" and when trying to create a new Date for example.

Can't find variable: window
undefined
Can't find variable: Date
undefined

Safari 1.3 (v312)
Does not occur when running in Firefox 1.0.4

Anyone have a solution? Is there any other way to hold onto Javascript objects when loading a new page? (not cookies, I didn't think they can hold objects, right?)

Thanks,
Philip Weaver
