Dirty Cells Red Icon missing in PQ Pro

[gammax500]

I just installed my pro grid and somehow lost the little red corner icon that indicates data has changed.

(I previously had the pro demo installed, and the red square showed).

I replaced the theme folder, and the core .js and .css files from the Pro Downloads here on the forums.

Please replace all the files, check the paths and refresh your browser.

I replaced all the files, emptied my cache and reran the grid, but the red icon is still not showing.  In addition, the cell in which i know data was changed does not have class "pq-cell-dirty" in Firebug.  What else can I check?

Also, the toolbar buttons show the correct number of changes made.  See screenshot
