I wouldn't say that was a bug -- another unimplemented feature 
(well, now implemented), namely searching the Windows registry for 
Rgui.exe when it's not in the path.

I guess that means you don't have permission to write registry 
entries under HKEY_CLASSES_ROOT.  In today's snapshot I have moved 
the relevant entry to HKEY_LOCAL_MACHINE.  You might see if you're 
able to get settings to stick now.

When saving the registry entry is enabled, you should only get the 
"File not found" error once, the first time you try (unless you 
type the correct path to Rgui.exe into gretl's Preferences 
dialog).
