When we apply the Advanced Layer Popup behavior to an element on the page, and it inserts the link to the external stylesheet, the folder name is wrong. It inserts a folder name of "styles" instead of "Styles" (the folder created by the extension). Also, if we go back in and change the style for our popup, it does not update the stylesheet link in the document to point to the new stylesheet for the newly selected style.

Extension Version 1.0.7
DW Version CS3 (Version 9, Build 3481)
Windows XP SP3

Figured it out. It was adding the updates CSS links further down the page in the code instead of at the original insertion point. Seems all I need to do is rename the Styles folder to "styles" and that should correct the issue.
