I searched aroud mantis but couldn't find anything about this

horizontal scrolling does not work for me in the call stack, locals, and watch list windows. The scrollbar is visible, but disabled (and shows that there is nowhere to scroll, even when window contents extend far beyond the edge and are hidden.) The only way I can get at that info is to widen the window, and sometimes the maximum width is still too small and stuff is hidden. Is this a known issue?

thanks,
David
