I have a situation where I'm creating a text file in my application, successfully closing it using FileClose, then using Run("notepad "+[filename]) to display it. All works well except that when I try to create a 2nd text file after that, the file is locked by PB unless I get out of my app. Below is an abbreviated example of my code. Does anyone know a workaround?

for li_loops = 1 to li_count
   li_FileNum = FileOpen("Recipient List.txt", TextMode!, Write!, Shared!, Append!)
   //populate ls_email_list variable from database view
   FileWriteEx(li_FileNum, ls_email_list)
   if li_loops = li_count then
      if FileClose(li_FileNum) = 1 then
         Run("notepad "+"Recipient List.txt")
      end if
   end if
next
