Paste error in dreamweaver 8

At time dreamweaver throws up this error " while executing DWShortcuts_HTMLSource_Paste command in menus.xml, the following JavaScript error(s) occurred: TypeError: MM.event has no properties" which does not allow you to copy or paste text in the application.

Heres the solution :

Go to this path C:\Documents and Settings\\Application Data\Macromedia\Dreamweaver
8\Configuration\ (these folders are normally hidden - you may have to use Explorer > Tools > Folder Options to unhide them)

Make sure dreamweaver is not running.. rename the configuration folder and restart dreamweaver and your are done..
