It's very simple, MS-Works database. I bought the first version when it came out, 1.05, and it had literally no bugs. The later versions have way too much fluff for my taste and after 6.0 bugs crept it. So I wouldn't recommend anything higher. Nothing earth-shattering, but if copy-paste via keyboard shortcut misses every so often that does get old. Especially when doing the year-end job. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam. Use another domain or send PM.

Then what on earth are you talking about? And why isn't the 100GHz figure - which you chose to emphasise by using it to name of this thread - a useful indicator of the speed of the part? -- Bill Sloman, Nijmegen
