I found a bug. I can't activate site changes to pubilc app. Below is descritption how I do this.
1. Open a editor site e.g. : http://demoauthor.magnolia.info/magnoliaAuthor/features.html
2. Change some paragraph
3. Click a 'AdminCentral' button
4. Activate chenged site
Everything seems to be OK. Yellow dot was changed to green, but on public there are old site, without changes.

The problem is on getHeader("Authorization") method in info.magnolia.cms.exchange/simple/SimpleExchangeServlet.java . When new window is opening (point 3) then this method return null value although I have access to Admin Central.

This problem affect in IE6.0, FireFox 1.0.3
