InfoQube has an option to open the last file on startup (Tools > Options > Program Settings > Modes)
 
While this is sometimes useful, at times it may not be desired. There are 2 ways to bypass this:
  1. Start the program with a /file command like argument. Typically, a batch file is used for this. Details to come
  2. Press and hold the Shift key while starting the program. Simple and effective
