After the update, I can't find the export to external editor function, I my case 'Sound Forge'. Anyone else found this or is it hidden somewhere else?
 
In fact my VST manager has disappeared as well. All the end of the Utilities menu has gone. Can access it through other means. Anyone else experienced this?

First time I have read about this. It seems
HKEY_LOCAL_MACHINE\SOFTWARE\Cakewalk Music Software\Tools Menu
may have been deleted somehow (registry cleaner?).
 
A re-install should get all the standard tools back but user entries such as SoundForge will have to be manually added back. I wrote a tool to make this easier. It is called SONARToolsEditor. A link to the program is here.

Scook, you are a genius. The SONARtoolsEditor has just returned the external editor (and the tools menu in the registry) to it's rightful place.
