Nope, this is still a problem in 6.1.2.
Much like the other posters, I only see this happening on the home page (skin is a modified version of the DarkNight skin).
All other pages work, just the home page.
Clicking on the login link on the home page, the pop up does not work (I assume from the js error) and instead get redirected to a login page.
It also prevents the home page from having working "Manage" popups except the very 1st one on the page.
6.1.0 did NOT have this issue, which is the version I keep rolling back to. I first noticed it in 6.1.1 when I did an upgrade.
Decided to wait until 6.1.2 to see if it was resolved, unfortunately it is not.
NOTES:
- This behavior occurs regardless of whether the ICONBAR or RIBBONBAR is being used for the control panel ops.
- This behavior occurs regardless of whether popups are enabled or disabled.
