SN8P won't let me use "File Open" to open multiple .snf files, but it will let me open different favourites -e.g. "Venus transits" and " Solar System" - in different viewers and I can use the "Window" pulldown to switch between viewers. See the first screen below. If I want to show the position of the earth and Venus in 2117 versus 2012 and open the "Venus transit" favourite in the "Solar System" window, then the SN8P window pulldown can no longer distinguish between the two window and the pulldown becomes inoperable. See the second screen below. What would be really nice would be to fix this problem and at the same time make the "File Open" function in a manner similar to "Favorites" so that I don't have to dump a whole bunch of file into my favorites folder to use them in this fashion.
