WebGUI Unresponsive / Hangs

[khancock]

I've noticed the GUI periodically hangs or becomes unresponsive when a WAN is down.  Is there a setting to change this behavior?  I've noticed this behavior on several boxes running different versions from  v2.0 to 2.3 running on Alix, APU or NetGate SG hardware.  It's really a PITA when you are trying to change the config while a WAN is down.
