We ran into a new display bug introduced within the last couple mojoPortal releases. The navigation menu in our skin started being covered up by the “Add File” button of the “Shared Files” module.

I was able to duplicate it on the mojoPortal demo site with the “Mitchison-earthy-alt1” skin. The good news is that it only appears to be an issue in IE7; or alternatively in IE8 running in “Compatibility Mode”… which leads me to believe its related to the ever elusive “IE z-index bug”:

Its possible this is an issue with the newer version of NeatUpload implemented in version 2.3.4.1... 

To reproduce the issue on the Demo Site: 

1. Log into the demo site.
2. Change demo site to the “Mitchison-earthy-alt1” skin (if it isn’t set already)
3. Create a new page called "Shared File Button Test" under the "Root".
4. Change the page order/move the "Shared File Button Test" to be between the "Events" and "Map" pages in the navigation.
5. Add a "Shared File" content instance onto the "Shared File Button Test" page.
6. Add a couple other pages under the "Shared File Button Test" page  (to give it a sub-menu). I recommend a long page title/names like "Test Cover-up Add File Button Menu #1".
7. Open the “Shared File Button Test” page 
8. Mouse-over the “Shared File Button Test” menu item to see the available sub-items (the goal is to "cover up" the "Add File" button on the "Shared File". 
9. Notice the placement of the “Add File” button showing on top of the sub-menu items in the navigation.

Anybody else seeing this issue/have a good solution? I've already eaten up a couple hours trying the various z-index tricks between my style.css, sitemenu.css and IE7Specific.css files. No luck so far...

Does adding:

.sf-menu li:hover{
z-index: 100
visibility: inherit
}
 

to the skin help?

If not, is there a way I can edit/add style files on demo.mojoportal.com to try to get it working?

Cool!  I found the fix at http://facility9.com/2008/07/17/ie7-dropdowns-and-z-index/ which was mentioned in the Google Groups thread you linked to.

No need to apologize.  I wasn't complaining -- just giving credit where due.
