I have did as you suggested and disabled the following...
Validation Toolkit, Universal Email, Digital File Pro and HTMLEditor.
This solved the that problem but now I am receiving another error.
When I go to alter or add a "Clear Session Values" I receive the following error.
Line 357 of "C://Documents and Settings-----------------WebAssist/Cookies/Library/WA_Configuration.js". getTagProp is not defined.
I have tried deactivating and deleting the Cookie Toolkit without success. I have also tried to reinstall CSS Form Builder 2 also without success. As well I have tried clearing the Dreamweaver's cache but the problem remains.
