I used my own cygwin before installing openAT V4.  
During the install, I got some problem because I do not remove my cygwin from the PATH … I reinstall it after and Open AT works perfectly now !

BUT I’m not able to run my old cygwin when I use open AT … or I’m not able to use openAT when I used my own cygwin … There is a cywin.dll conflict !

Does somebody have the same problem ?  
Any idea to resolv it ?
