Maybe it was "Permission Denied"... I just meant that happens when the mouse is in "contact" with the focused window. It can be moved from a synchronized dialog window, but it's complicated & not usually worth the trouble, methinks.

Ok, I wanted to make sure again: it's "Access is denied". The error only happens if the window has capture, such as with onmousedown; while resizeTo or moveTo work for me with onclick. I don't think it's a security issue, either, because that also happens in HTAs.
