One other thing that may or may not be related. While ending the sim to go to desktop and run SH3Gen worked normally, returning to SH3, my Saved Game would not reload completely. It would get all the way to the moment before "Not so long ago", but screen would stay black. Then the Microsoft "Send or Don't Send" error app would appear with the error being something wrong with the kernel32. But I found that restarting SH3Cmdr to restart SH3, and simply closing the pop-up window to "Generate" SH3Weather would allow the saved game to reload properly.
But there was never an apparent problem using SH3Weather when the Saved Game problem occurred. The Mission.dat (? or something like that) would state to be updated. My not generating the weather was just a routine process of elimination to solve the problem. And I got lucky first try.
But, I digress...the planes, jimbuna. The planes....
