Hello listers ! Greetings from Paris ! Dear Allin, after installing winsnapshot, everything runs ok. all my scripts are correctly executed. Concerning the slower loading time, it is no longer here also, so all is right now. Thanx for the quick fix ! I am currently working on AIDS and QUAIDS estimation scripts. When they are ok, I may contribute them if you are interested. Cheers folks !
