When you right-click on an .fpx file and choose 'configure type', is the value for 'Load Using' set to 'LEAD Tools'?
That's the default and is supposed to work. If it does not, try setting it to Poly Image and then try to thumbnail those files again.

Sure - if the above doesn't help, feel free to send me a sample (one should suffice). There should be a little envelope icon next to my name with my email.
