title: How to start the associated program when selecting more than one files?
body: <p>I have set .jpg file associated to my own program. I want to add the context menu to .jpg files, so I set the entry of HKCR.jpg\shell\open\command to "myProg.exe %1". After associating, there will be an item on the top of the context menu saying "Open image with myprog". This works right when I select a single .jpg file, but when I selected more than one file and click the top item of the context menu, nothing happended. How can I solve the problem?</p>
  
  <p>Thank you very much</p>
