mouseEnter/mouseLeave Problem

[Lynch, Jonathan]

Similar to what I put in another message that I just sent in...

If you maintain a global variable to keep track of the graphic that is
set to blue - then, whenever you set a new graphic to blue, you can make
sure the previous graphic, whose name is stored in the global variable,
gets set back to black.

I believe that mouseleave is also not called while the button is still
down. And now that I looked it up in the docs, even using mousecontrol
will not work (as used in the suggested script I just sent), because
that remains the original clicked control, even if you have moved over
another object, until you release the mousebutton.

You might have to resort to checking to see if the mouseloc is within
the rect of each graphic you wish to check - ugh.

I don't think so, cos it's mouseLeave that isn't being called.

If both rectangles are black and I move the mouse back and forth 
between them, all works as it should. If I mouseDown in either of the 
rectangles and then move the mouse to the other recangle, the 
Rectangle moved to changes to blue BUT the rectangle that has just 
been left DOES NOT get the mouseLeave message. Once this has happened 
once, the behaviour goes back to normal again, e.g. the rectangles 
change color and you would expect again!

This really seems to be to do with interaction between mouseUp and/or 
mouseDown and maybe mouseStillDown. If anyone could shed some light 
on this I would be really gratefull I just can't seem to work out why 
this doesn't work???!!!

Thanks in advance for any help
Dave
