XLS in internal viewer

[magnus]

I am trying to configure UR to display and edit .xls files in the internal viewer. In the options, browser tab I added the .xls extension to display in internal browser view.

On the options, documents tab I added the .xls extension to open stored documents writeable.

When I click on an .xls file in the data explorer pane I am promted to either open or save the file. Clicking on open will launch Excel externally and open the file.

I am running UR ver 2.0c from a USB stick on Win XP pro.
