I run Excel 2010 at home and at work and I am usually happy with it. I even like the ribbon over the old user interface.

However, every now and then I get a interesting problem to analyze and I usually end up with a sheet full of calculations, charts AND ActiveX scrollbars. The scrollbars are for changing various parameters and as the charts are updated almost in realtime it helps me understand how things work together. Well, at least it used to be almost real time back in the 2003 days. Even though, as everyone knows, Excel 2010 was a huge step up from Excel 2007 it is still nowhere near the speed of Excel 2003 when it comes to updating charts affected by ActiveX scrollbars (despite that we now have so much multiple giga bla bla).

I'm considering buying Excel 2003 but a while ago I stumbled upon a old PC running XP and Excel 2002. How fast it started when double clicking a .xls file almost had me jump out of my chair.

Now for the question, is Excel 2002 noticeable faster than 2003 when it comes to charts and sheet calculations? Will either of them run on Win 7 on a 64 bit machine?
