Does anyone know what "The floater" is?

I just installed CS5.5 for the third time, and still get the error message:

"Unable to find file floatui.htm in the Configuration/Floaters directory.
The floater will not be shown."

when Dreamweaver is launched.

The program seems to work OK as far as I have been able to test it. All the floating windows appear when called up.

System is windows 7 64 bit

This happens when the installation is downloaded from the web or when it is installed from the DVD. Same happens if it is uninstalled first and the machine restarted prior to a subsequent install from DVD.

Adobe technical help suggested that I re-install it, and also that I should rename the configuration file, but they were not exactly sure where this was located.

Eventually it was decided that I should rename a folder called Dreamweaver CS5.5 in the configuration file that was in ....users/current_user/Appdata/Roaming/Adobe/ which I did, calling it Dreamweaver.old, and restart the program, which I did- with the same  result.

There is no ..Configuration/Floaters directory in that path at all, but there is one in Programfiles(x86)/Adobe Dreamweaver CS5.5/configuration/

However, this does not have the file mentioned, and a search of the entire computer can't find one either.

So how do I get rid of the message? Insert a file with the correct name in this folder?

Or is this just a quirk or an error in the DW installation script?
