Pdf preloader

I don’t know if this is even possible, but is there someway to make a preloader for a pdf file opening? I’m not talking about the actual download of the file, but the file opening?

Here’s the problem - I have a flash projector which uses fscommand to open up my pdf files. I’ve reduced my pdf files sizes to practically nothing and yet it takes forever to open up the pdf files. It’s not my computer, because I can open up the direct pdf file very fast. It’s only when the projector is up and running and I click on a link, that adobe takes a dump. It takes more than one minute to open!

I wasn’t sure if there was some way to embed the pdf file and then make a preloader for it when actually opening or if there was any other way to do this.

Anybody out there have similar problems?
