IE7's dev tools are virtually useless. Is it possible for you to investigate
in another browser? If so it would also be useful for you to see if this
issue is specific to IE7. If you have IE8 or IE9, you can use them with the
Document mode set to IE7 to get an experience as similar as possible to IE7,
but with better dev tools.
Other things worth investigating - does this issue only affect your user, or
are all users unable to switch dashboards? If you remove one or both of your
existing dashboards, and create two fresh, empty dashboards, are you able to
switch? What exactly happens when you try to access the dashboard switcher -
nothing?
