Nope, both 1 and 2 are launched from the same folder
a,b,c,d are all launched from a 2nd folder (on other HD)

and its the folder on C (which holds 1 and 2) that has the wrong config resolution

and the problem is there even if i don't 'launch' a, i just have to add it in maximizer, and then '1' stops working on 1920x1200.

So to sum it up:

1 and 2 made, both launch from folder 1 on HD 1, both work fine
1, 2 and a made, i launch 1 (ONLY 1) and it already makes it 1919x1199. As soon as i remove region 'a' from maximizer 1 works again. Don't have to actually launch anything else than '1' to get the resolution 'bug'
