Something in your environment has turned on "novice" mode (or turned off expert mode). If you go to Options->User Preferences (in the CIW), there's a checkbox there called "Options Displayed When Commands Start". If that's on, you'll get the behaviour you describe.
This can be controlled a few ways:
hiGetCIWindow()->expertMode=t ; is the same as
envSetVal("ui" "showOptionForms" 'boolean nil)
My guess is that you have a .cdsinit or .cdsenv file which is setting showOptionForms to t, or expertMode to nil.
