This is annoying in general in that the very instant I mouse off the 
image the popup leaves. What would be more ideal is a 500ms timer on the 
popup hide function. This would allow you to refocus on the popup and 
that focus would cancel the pending hide. This gives a much more 
forgiving navigation in general and would solve the screen magnification 
issue. What's funny is that mousing over the  'wedge' which forms the 
thought balloon still retains the popup's state, but beyond the wedge 
into the main body of the balloon pops it.
