I have not changed any of the Windows settings. In version 32, the position of the help window was saved.
I just opened a TCC32 session. The F1 key opens the version-32 help, and the window size and position is remembered. So this is some specific to version 33 on my computer.
I had been invoking help inside TCMD. I just tried it in a detached TCC33 window, and the help always opens in its original position, even after I changed it.
