I bounce back and forth from norm entrenchment to it's dev.exe version and understand the reset there, but damn it...
Well, use playonlinux... you can install several time the game... since it use prefix, each install have his own virtual drive with his own configuration...
I use it for play mod who need older sins version...
For the crazy one who find the game not enough challenging, it is possible to make two full prefix install and run two game in windowed mode in the same time...
As for the windowed mode, 1024x768 is the smallest one who don't crop menu... as for other bigger size, you have not limit in your choose... move your mouse cursor on the right lower corner of the windows ( near the version number )... when you cursor turn in a diagonal double arrow, push the left mouse button and move... it will resize your windows to your own wish, need less that 1 second for the game adapt to the new resolution
