modal not receiving focus or reaching top

What steps will reproduce the problem?
1.at URL http://www.threepointfix.co.uk/charts/openlayers.html
2.works fine on IE, but in FF, it seems like the modal isn't reaching the top, 
and never receiving focus, so can't be acted upon, closed, or viewed.
3.

What is the expected output? What do you see instead?
As per the IE version, which works perfectly (except one small CSS issue on one 
modal - but thats for later)

What version of the product are you using? On what operating system?
running nyroModal 1.6.2 on XP, IE 8 and FF 3.5.15

Please provide any additional information below.
Adding any sort of Doctype declaration causes IE errors,but not within FF, but 
doesn't resolve problem. I've tried playing with zindex settings in css style 
sheets, and also setting zIndexStart to various different numbers, but to no 
avail (I may be missing the appropriate setting though!).
I also, to be certain, tried add a jquery.noconflict but that caused nyromodal 
to load into the main window rather into a modal, and in the case of IE, also 
failed to pass the form data correctly... it doesn't 'feel' like a jquery 
problem to me... more like a conflict somewhere else between nyromodal and 
openlayers
I'm relatively new to js, so it may be something obvious... but after 2 days of 
hunting around, i'm beaten!... any help would be really really appreciated.
