Crash on Using Horizontal Scroll Bar

[Karen Robbins]

Moving the horizontal scroll bar results in a crash with the standard 
error message that FM (11) has to shut down. Sometimes after 
restarting the horizontal scroll bar behaves itself; other times, it 
does not.

I am not doing a particular task immediately before; it can happen 
after first opening a document, after a task, whenever. Obviously it 
occurs mostly in zoom views when the scroll bar is more likely to 
come into play.

Is this a known issue and is there a solution?

Thanks,
Karen
