RT Users

For consideration/ideas before a bug report is filed.

Our users are reporting that IE8 does not work with our
RT 4.0.4 instance (after upgrading from 3.4.4 last week).

Chrome, Firefox and everything else about our RT 4.0.4
setup are working perfectly fine.

Our RT 4.0.4 instance is brain-dead simple/stock. Apache
PostgreSQL 8.4.9, and mod_perl2 as provided by RHEL 6.2.

USER ONE

  1. Login
  2. RT at a glance shows fine
  3. Simple search: ldap
  4. Four tickets returned.
  5. User clicks one of the tickets
  6. Ticket takes 30 seconds to display, redrawing the window
    several times in the process (Chrome for same ticket takes
    only 3 seconds to display the page).

USER TWO

  1. Login
  2. Clicking any ticket causes browser to hang for 2+ minutes
  3. Task manager --> kill IE

There is at least one existing bug report for this. It may be marked
resolved already.

One of the major problems is an interaction with IE8’s compatibility
mode turned on and PIE.htc (a CSS3 compatibility layer). Turning off
compat mode or removing PIE.htc from your install should fix the problem.

How will removing PIE.htc affect the non-IE8 users?

PIE.htc is only used for IE 7 and 8. Without PIE.htc, one of the things
IE 7&8 users won’t see are rounded corners, for example.

Look in the mailing list archives and the bug tracker for more
discussions about this.
