Strange...but it does the job and that's all i ask.

I had to use the same trick :

:ConqueTerm CMD /c "perl -Ilib /my/scirpt.pl"

I'll tweak it a bit more tonight or tomorrow, to try and integrate it in my Vim framework. Exciting !! =D

PS : i've been playing a bit more, i don't understand its behavior. The screen flashes black and white somtimes, there's often a bug from Vim, and sometimes it behaves as expected.
