[Lazarus] horizontal scrolling in gtk2

[David Emerson]

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
