JavaScript error while loading Dyn TextField.htm

Here is an interesting one. I get the following errors when working on the attached file, spinner_rex.php, on my desktop machine using DW CS5.5 0n Windows 7:

The DynTextField script does not define the findServerBehaviors function.

OR

JavaScript error while loading Dyn TextField.htm:

At line 54 of file "C\Progam Files(x86)\Adobe\Adobe Dreamweaver CS5.5\Configuration\Shared\Controls\Scripts\TagMenu.js":
The user chose to stop the script.

OR

A script in file C:\Program Files (x86)\Adobe\Adobe Dreamweaver CS5.5\Configuration\Shared\Controls\Scripts\TagMenus.js has been running for a long time. Do you want to continue?

I deleted WinFileCache-9287E01C.dat but still throws errors.

I do not get the above errors on spinner_rex.php on my laptop machine using DW CS5.5 0n Windows 8. I have Data Bridge 1.1.8 and eCart 5.0.7 (planning on installing eCart 6.0 soon) on the desktop machine that throws the errors but no extensions loaded on laptop.

Perhaps this is unrelated but when I open DW CS5.5 on the desktop machine I get two error messages: Unable to find file WA_Memento.htm in the Configurations/Floaters directory. The floater will not be shown and Unable to find file WA_SiteTools_Progress.htm in the Configurations/Floaters directory. The floater will not be shown.

Annoying but not life threatening issues. Thank you as always.
