I've been working with silverstripe in combo with imagegallery and Shadowbox.
I always though that it worked fine and it does in FireFox. But today I tried something in IE and i found out that shadowbox isnt showing correctly in IE8. (havent tried 7 or 6).
So first thing i did was going to the shadowbox website to see if it is a shadowbox problem. But on this site it works fine in IE8.
The problem is that the modal screen isnt extended to the bottom of the page if the page is scrollable. If you scroll the opened image should scroll along and the modal (black transparent div) should also scroll along. But this doesn't happen.
You can check http://silverstripe.fg-photos.net/sunrise-sunset/. I use resolution 1280x1024 and i need to scroll here. Just open one of the images.
I hope you can help me out because ive checked the JS of shadowbox and found that the JS file does use:
document.documentElement.clientHeight and window.innerHeight
As far as i know (and ive implemented it in other sites) this is the correct way to have both FF and IE.
Hope you can help.
