I have an older machine to a certain degree. It had been acting extremely slow lately. A friend recommended I try eBoostr so I joined this Beta test team. I do a lot of work with very large pdf files and what would normally have taken me days or weeks to do because I would have to waite for the computer to refresh for 5 or 10 minutes every page now takes me hours. Thank You! MAJOR DIFFERENCE! Your program is great in my book.
