You mean, of course, when debugging within the design environment, right?

If so, it's the same process you'd use when hiding the standard toolbar. Namely, something like

IF WEXIST("PROJECT MANAGER")
  HIDE WINDOW "PROJECT MANAGER"
ENDIF

When exiting

IF WEXIST("PROJECT MANAGER")
  SHOW WINDOW "PROJECT MANAGER"
ENDIF

My Is_Run() doesn't check child windows. However, the _VFP system variable can tell you how many projects are open and give you a reference to the current project via the ActiveProject Object.
