Hi all, i overheard someone talking about how they can put several screens in to one browser i.e you click your browser and have 4 screens within one tab.
Don`t be confused with I.E 7.0`s and firefox`s multitab versions, i literally mean 4 windows open with just one click. Does anyone know how or what piece of software is used to do this?

P.S I don`t mean the cascading windows either in the toolbar section.

Thanks for any help with this.See page 4 of this PDF, the part TITLED Getting Internet EXPLORER to Automatically Open All Tabs You Had Running When You Last Used It.  Does that help?  I believe this still opens multiple tabs, but opens them simultaneously.  I don't know how you can open multiple sites in one tab.it's not QUITE clear what you want but i have a great little add on for firefox called Split browser which gives you something like this

is this what you want?That is really cool, gonna try it out hyperhedron.
I love firefox and it's add-ons

EDIT: Split browser was chaos and ate at my RAM, LOL. I uninstalled it....no need  The OP may be REFERRING to the IE7 Quick Tabs (View==>Quick Tabs). It gives a nice visual summary of all the open tabs.
