I tried that, and Take Command vanished. From then on I could not run it at all. It must have gotten positioned entirely off the screen. Finally I had the idea to run ACTIVATE "TC 10 *" MAX, and that made it reappear.
I'm not trying to make frequent changes; I just want TC to come up with a standard size and position. Also, after using an LCD projector, the window gets messed up, and I'd like to have an alias that will restore it to the original configuration on my high-resolution laptop screen. (The other way to prevent that problem is to close TC before sending the video to the projector -- just minimizing is not sufficient -- but I often forget.)
