Problems when paginating search results

[eluser]Wayne Smallman[/eluser]
Hi guys!

I've created a search tool that has pagination, and which uses the set_flashdata() function to keep track of the various pagination options between pages.

All works fine until you open an entry and then return to the results page, at which point, the pagination options vanish and the whole thing stops working.

I kind of get the idea the persistence of the pagination options are dying the moment an entry is opened. Fine. But it does this even if I have the entry open in a floating box, a la Fancy Box, or if I open the entry in a tab.

Any idea how to stop this unexpected behaviour?
