Requiem: A Total FL Conversion Mod .
http://mod.pff-clan.us

I talked to a computer guy at work about this. He thought that if you minimized FL, there might be a message on the screen asking if you want to connect. Since I don't have VISTA, I don't know if this is true. I doubt, if the answer is that simple.

I'll try that tomorrow.

Did it work?

If there's a message then i didn't see it. When i minimized it i didn't see anything on my desktop so no.

I am copying this from www.starfyrestudios.com. Reyen Starfyre wrote this. Reyen helped create the TNG 2.76 mod.

"I've got some good news, I've been able to get FL to run on VISTA Home Premium.

I'm in the process of going through the whole campaign to see if there are going to be any bugs. Tis a good sign that VISTA users will be able to use FL. For VISTA users, run as an adminsitrator and have user account control turned OFF. Sometimes if you run it in compatability for XP SP2 that helps also."
