Sorry I noticed this bug early but corrected it locally and forgot about 
it...

This is a CSS issue for property z-index :
 #bar : 100
 #minimap : 100
 #background : 102
 #window : 103
 #rubberband : 99

I added 400 to those number (100 -> 500) but adding more should be better.
Suggestion :
 #bar : 10000
 #minimap : 10000
 #background : 10002
 #window : 10003
 #rubberband : 9999

Someone with 10000 tables in his database might not wish to display it...

For info zIndex is not limited, but the good practice is to limit its value 
to less than 32000.

A better workaround is to define position:absolute or position:relative for 
#area, but it may brings some side-effects.

Acknowledged. I will try experimenting with alternative positions prior to 
increasing
z-index to some insane high levels :)

Fixed in r91. All controls are now grouped in a dedicated layer, whose z-index 
is
dynamically adjusted as necessary.
