This is fixed. I don't really want to talk about it, but here's the 
CVS commit:

This happened in the past with popup windows where we didn't use the 
following code:

name = window.open(url, name, options)



Maybe something similar is necessary for iframes?

Versions:

---------------

Kronolith: CVS HEAD as of 2/20/2006

Framework: CVS HEAD as of 2/20/2006

Server: LAMP (FC2, Apache 2.0.58, MySQL 3.23.58; PHP 4.3.10)

Client: Windows XP

Browser: IE 6.0.2900.2180 (does not affect Mozilla)

Tested using multiple skins: bluewhite, mozilla, simplex



Summary:

--------------

After using either of the previous/next navigation arrow buttons in 
the week or month calendar view, all links in the sidebar cause IE to 
open a new browser window rather than writing the content of the 
target page into the horde_main frame as expected.



Links in the sidebar are restored to normal operation only after logging out.



Procedure to recreate bug:

-------------------------------------

1) Login to Horde using MS Internet Explorer

2) Select "Calendar" from sidebar

3) Click either "Last" or "Next" navigation arrow in week or month view

4) Select any item from the sidebar



Result:

----------

All sidebar links now open in a new browser window rather than 
resusing the horde_main frame. The user must log out and log back in 
to restore normal sidebar operation.



Workarounds:

---------------------

We have suggested to our IE users to either switch to a 
Mozilla/Firefox browser or to use the "Goto" calendar button instead 
of the navigation arrows.



Analysis:

-------------

We have done some cursory review of the HTML templates, JS, and CSS 
looking for clues, but have come up with nothing obvious that would 
cause (or correct) this behavior.



Has anyone else seen this kind of framing issue?
