I just re-read your solution. You got it. Interestingly, using the Clear option on from the Edit menu does invoke the same sort of response. Like the above, the command window is cleared only until the next line is typed. So the context menu is calling something different to clear the window. Foxtools (as I said) before doesn't expose anything that'll allow you to emulate this. The only other solution would be the mouse_event() (to simulate the right click) then the KEYBOARD.
