There is something not compliant with the new javascript on that browser. This is why you get the right panel on top of everything. The resizing doesn't work as expected. I will have to check into that to see what could be in effect. BTW, this is new to me. Does this mean you were using another browser during the test phase or you just forgot to mention it? :)
