Greybeard, I have had the same experience. It was part of the problem discussed in this thread:
http://www.subsim.com/radioroom/showthread.php?t=205755
I hesitate to fault the mod, since 1) it is TDW's work, and I know that he is thorough and conscientious, and 2) there is evidence on SubSim that lots of people use this mod and only a few report problems. But I am pretty sure that something in the mod conflicts with something in
my setup. Honestly, though, I have never tried to pin down the problem any further. I just don't use the mod. A pity, too, since, like all TDW mods, it's a big improvement. But I was so happy just to get my game back to a playable state that I haven't done any further troubleshooting. (This mod wasn't my
only problem!)
