Aaaargh! Linked to the previous content instead of navigation
I have a real-estate site of a client's and it has a big bug which is beyond my scripting skills.
The user submits a search form and is shown the results of the property's (houses). They then click on the desired house and are taken to the page which the relevant content. All good.
Then they use the browser back button, as everybody does, and is taken back to the search results, page 1 of results, or page n of results...whatever. All good.
If the user selects another page of results from the navigation
e.g.   
instead of directing the user to the page n of results page, the user is taken to the last viewed property (house) page. ??!?!?!?
I know alot of you must be thinking its me incorrectly scripting...but the wierd thing is that this bug only occurs in FF and doesn't occur in IE...(only checked 8).
It's doing my tits in and my client is making an issue of it. BTW I'm using VBscript aswell to insert variables (pageID).
