well, has someone tried it with safari? don't ,know if it even works, they've added some Ajax there, to make it a bit nicer to browse, but looking at all this standalone JS functions (no tree, no framework) & knowing as an universal true that IE SUCKS, it is normal that it get bloked sometimes, to avoid that, the JS will need to be redone, organised & more important, hierarchised. For the time being, the best thing todo is always the same, USE FIREFOX, avoid the IE crap in all the ways you can...
