Howdy, all;

Having some trouble with Calibre calling external viewers under Linux.

If I'm using a KDE interface, I can see external viewers for PDF, ODT, HTML, whatever -- just fine.

If I'm using the LXDE interface, nothing is called; I cannot use any external viewer. Each external program is properly set-up and associated with the proper types of files (both by filename and by 'magic number').

This is the same physical machine; just the user interface (KDE/LXDE) is changing.

Is this a known issue? Is there a workaround?

Thanks!
