I can`t tell you how long it took me to move up from Photoshop 7 to CS5 Photoshop. As long as an application is working for me or serving the purpose for which I got it in the first place, I see no reason to upgrade.
Firefox was putting out a new version every sjx weeks...just when they got the bugs out of it, a new version was available. It`s only a "browser"...there are several good alternatives to Firefox.

If i can't solve this current problem, I will try some others, but reluctantly, because I have been using Netsape since, I believe, 1995.
