I used keylight to key out a blue screen. When I clicked on the blue screen using the eyedropper, the actors become somewhat transparent as I can see the layer beneath the actors' layer. I tried clicking on different parts of the blue screen and the same thing happens. Why is this happening? What can I do to keep the actors from being semi-transparent. Thanks and God bless.

You need to check out some tutorials for keylight. It's not just a matter of picking up the color with the color picker, but of adjusting the parameters of the plugin. Here's some useful links:

Here's a very handy guide to keying that everyone should read.

Also, there are other ways to key besides using Keylight. And many times different parts of a shot need to be keyed in different ways. Sometimes with different effects, but certainly diffeerent settings. Usually the pros use different keying for hair than for the body and often different body parts get keyed differently. (See this tutorial.)
There's a lot of good information and a lot of useful links on keying here. There's also a whole section of keying tutorials here at Creative COW.

Hey, that's a pretty darned nice set of tips you found on General Specialist, Michael. Thanks for posting the link: I just bookmarked it.

My only problem with that link is that the address has the word cial----is in it, so my posts keep getting delayed for moderation. As if I, an active member for many years, has suddenly become a spambot. On the one hand, it's kinda funny, but I often don't post that link because the filter irritates me.

Yeah, I ran into the exact same thing. Apparently, the COW has issues with older males who want to have fun.

To avoid that same annoying message, I stopped using the phrase, "why don't you just cr*ck open the manual?" The COW has issues with more than one kind of medication, it seems.

It's not medication they object to in your case; it's illegally obtaining software keys.
