The following important options in the article details section are greyed-out/non-editable when I try to add a new article in Article Manager. (i.e. Article Manager: New [ New Article ])
o   Magazine:
o   Issue:
o   Content Category:
o   Article Manager:
When I use the content wizard to add new articles everything works great. Once the articles appear in the Article Manager all these options are now fully functional when editing. Any suggestions in resolving this anomaly would be greatly appreciated!

Note: I am currently using iJoomla Magazine  Version 2.0.17c. This occurs in both IE7 and Firefox 3

Okay, simple solution...

After you enter text in the "Heading:" areas just hit "Enter" on your keyboard and no more grey; these area are now editable.

Maybe this is a bug with Firefox 3.01...
