As filed on bug 456376, the toolbar for editing form doesn’t appear to the screen after MDC/Deki 8.08 upgrade. And, it depends on the scrolling position of the screen. Immediate aftermath we click the edit bottun, we can get the toolbar, but after scrolling down to the bottom, it disappears. For the pages with a large volume of ToC, we cannot use the toolbar buttons.. (Of cource, we can view the toolbar with scrolling up,, but it’s not usable :-p)
It seems that this might come from some bugs at customized js, b/c i found that the div which wrapps the toolbar gets some queer relative position when scrolling. But i could not figure out where is the actual problem..
