[ka-Map-users] That grabbing hand cursor...

[David Badke]

In Firefox 1.5, I get errors in the Javascript console (using the 
Console Filter extension) whenever the grabbing hand cursor switches 
from one state to the other ("Error parsing value for property 
cursor."). I tracked it down to the cursor definitions in kaTool.js:

    /** the cursor to use when the map is not being dragged */
    this.cursorNormal = ["url('images/grab.cur'),move", 'grab', 
'-moz-grab', 'move'];
    /** the cursor to use when the map is being dragged */
    this.cursorDrag = ["url('images/grabbing.cur'),move", 'grabbing', 
'-moz-grabbing', 'move'];

It's the 'grab'/'grabbing' values that cause the error (in 
kaMap.setCursor). Changing the order to:

    /** the cursor to use when the map is not being dragged */
    this.cursorNormal = ["url('images/grab.cur'),move", '-moz-grab', 
'move', 'grab'];
    /** the cursor to use when the map is being dragged */
    this.cursorDrag = ["url('images/grabbing.cur'),move", 
'-moz-grabbing', 'move', 'grabbing'];

eliminates the error, at least in Firefox (haven't tried it in IE). I 
assume 'grab'/'grabbing' is meaningful in some browser, but Firefox 
really doesn't like it. The cursor does display correctly, since Firefox 
accepts '-moz-grab'/'-moz-grabbing', which the setCursor function gets 
to eventually.

This does tend to fill up the console with bogus errors. Could the order 
be changed as above?
