When I select a workspace that does not have the need for a JavaScript engine I get an error message saying that I need to upgrade:
WebApp Version Conflict
The JavaScript Engine in this workspace is out of date and should be upgraded to the latest version.

Workspace JavaScript Engine Version =
Master JavaScript Engine Version =

Update JavaScript Engine?

How can I tell the studio to just ignore the JavaScript Engine?

I have deleted all files under AppHtml except global.asa and the .wso files.
