Ok, see my other reply about what is happening about doing two 
checkouts on top of each other. I just wouldn't do it.  I need to do 
this often enough, I never touch branching. My projects are all 
rather smaller, developer wise that is. Its generally me, with one or 
two others. The code bases are medium sized, maybe 200-1000 some 
files total for each project. But since I am the main developer, and 
CM for this stuff, it makes it a LOT easier to do without branching. 
And everyone sort of works in their own area.

Anyways. Try something like this

#check out your "initial baseline" build, which was called LIVE-REL-2-3
cvs co -r LIVE-REL-2-3 mymodule

#Now update what you just checked out with the files checked in with 
the tag BUG23
cd mymodule  #the package you just checked'out
cvs update -dBUG23

That should all there is to do. Hope this works.  I may be missing 
something, different projects can vary so much, there may be a slight 
twist to it that will make it work better/worse for you.
