>>Hmmm, who advised it? I hope it's not my case... I'm afraid it could be something my son installed. As far as I recall last time I used RDP was Friday, I made some fixes in my code, then let my son play for ~ 1h. while I was preparing for Shabbos... When I tried at Monday night, it didn't work, and it didn't work since then :(

I'm not sure I want to do that. I've installed some staff later.
