Graham,

Have tried setting the association in Windows Explorer itself?

I don't have Windows 7. In Vista the process is as follows ...

Navigate to an .SGU or MGU file and right-click on the file (#1), select "Open With" (#2) and then select "Choose default program" (#3). These numbers are marked on the image below.



On the window that pops up, select "Browse ...



... and then navigate to the \bb folder and select BBW.EXE. "Ok" your way out of all the windows.

Now double-click on the filetype you've just set and see if it opens. Note, .SGU and .MGU need to be set separately.

Hope this helps,
Noel
