Bug Description:

a sepearte issue from bug#7148295 - 7u4 wont load applet on Chrome.

After fix the hanging problem on bug#7148295, you be able to login but
not the "serach" link issue which is a separate issue and need to be fixed.

The customer frame becomes undefined after visit any of
those three search links,
but not the "list" links. Looks like there
are some operation in applet cause
the frame to be freed for Chrome.

The problem is Chrome specific, and seems to be related on reference
counting on
JavaScript object. What is interesting is that this is
only a problem on Chrome,
and only for those search links.

The same test case and an EPF in bug#7133019 can authenticate
to their portal
running
 Truepass and reproduce the issue.
