This might be my end but cannot get menu to work on Blackberry Playbook, whichever one is clicked it just refreshes page, no drop downs or anything? 

Hi Miles,
You may have to work with me to fix that issue as I don't have a Blackberry Playbook to test against?
Are you using any particular browser on your Playbook? 
Chunks 

It's the default browser and one called 'origami' both just refresh page or do nothing. Asks to enable webGL.
Have Googled which browser is default but can't seem to find a name. 

Was it all the menu drop downs that don't work or just the fixtures one?
I've changed the fixtures one as that was refreshing straight away but the others should have been fine?
I'll see if i can find an emulator to sort a fix. 

Getting there, the actual menu is now working, but dropdowns are behind the other page elements and not accessible. Maybe just a z-order change will fix it.

Does the menu change when you view the site in portrait mode to a mobile menu?
I'll check the z-index... 

Yes menu changes to stack, then retracts to just menu. Nothing else until I rotate screen. 

Does the menu now sit on top?

Unfortunately no. Still the same. Have refreshed/reloaded page to make sure wasn't a cached copy. I did have this problem on our old website, had to put whole menu in its own transparent layer on top of everything else.

Strange as thats effectively what i've done, the menu is in its own div with a z-index of 9999 and the everything else is back down to z-index's of 0,1,2, etc.
I've tested on Windows 7 in IE9 and it looks ok there for me.
Are you able to send a screenshot of the problem [email protected] 

Screen shot emailed.

Now  working :)
