mhack=false creates two mouse cursors, one within the CNC window that doesn't work, and one outside of the window that does work.
I tried to download and run what you showed me, but it just asks me to insert the CD, so I don't know whats going on there.
*EDIT* figured out to set no cd mode manually, why I had to do it manually i have no idea, the game will run but when i try to click on stuff it locks up and remains frozen, I have to use task manager to shut it down seems like I can't play it.
I did get this working WITH the FMV pack just ONCE. I have not been able to get the game to run since then, so something is really wrong here and it is exactly like the last time on my old laptop, it will install and operate just once, then never work again unless I reformat.
