I've just downloaded GNUstep onto my Vista machine, installing the GNUstep MSYS System, GNUstep Core and GNUstep Devel components mentioned on theGNUstep website (http://www.gnustep.org/experience/Windows.html). I installed into the standard folders but when I try to open the shell for GNUstep the window flashes up and disappears again.

I've checked the PATH variables and minGW.exe and the GNUstep components show correctly.
I've found very little on the net to help with the problem. Can anyone provide some advice as to what could be wrong?

Thanks in advance,
