Re: gEDA-user: "click on zoom focus"

[David McQuate <mcquate@xxxxxxxxx>]

I've just discovered the condition that causes the problem.

Usually when I operate the scroll wheel to change the zoom, PCB 
immediately adjusts the display, zooming in or out.  Usually I can 
quickly go several steps in or out, rapidly, without waiting for the 
display to be updated after each click of the zoom wheel.

Sometimes, when I move the scroll wheel one click, the menus gray out, 
and the "click on zoom focus" message shows in the status bar.
If I click anywhere in the layout, the zoom update proceeds.  *However*, 
if instead of (left-clicking) somewhere in the layout, I instead move 
the scroll wheel one additional click, the menus and left-hand panel of 
buttons becomes locked grayed-out.  I can continue to zoom in or out, 
but right-click panning doesn't work.  The "click on zoom focus" message 
has been replaced by the normal "view= component  grid=25.0:0 45_/  
line= ..."

So the problem is associated with a change in state from one in which 
multiple zoom steps can be completed rapidly, and one in which the 
program asks for a "zoom focus".  Why does it "think" that it doesn't 
know the point about which it is to zoom?

Thanks to all who have contributed to this thread!
