[cisco-voip] 7936 randomly not generating certain portions of the HTML admin page

[Robert Kulagowski]

When I use the admin web page of the 7936, I get all sorts of anomalies, 
like occasionally the top page of the page will say "The page cannot be 
displayed" rather than the listing of the firmware version, etc.

The left-side icons also usually sometimes come up, sometimes not.  If I 
do a shift-refresh in IE, I'll usually get some of the icons to fill in, 
sometimes not.

Is this a known issue?  Firmware 3.3.11 and .12.
