I use MultiMon (free version) (
http://www.mediachance.com/free/multimon.htm) to manage my 2 monitors. MulitMon puts a button next to the "minimize" button on the window frame that allows you to easily send a window to the "other" monitor. With Lunascape 5, the MultiMon "move window" button cannot be always be seen in the window frame, but when you click anywhere on the "minize" button other than the far right-hand edge, the minimize button does not get clicked, but rather the MultiMon button gets clicked. I do not have this issue with any other window.
Thanks,
Eric
