I have configured the Windows 7 registry to open no-extension files with emacs via
"c:\program files\emacs\bin\runemacs.exe" "%1"
Left-clicking in Windows Explorer on a file with no extension opens the file in emacs.
Left-clicking in Dopus on a file with no extension pops up a "Chose the program you want to use to open this file" window with emacs as the only choice.
The Windows Explorer context menu for a no-extension file show "Open" at the top.
The Dopus context menu for a no-extension file shows "Open With ..." at the top.
How do I get Dopus to open a no-extension file directly?
