One case of OLD software - Quickbooks Pro 6...

I'm running QuickBooks 2006 on SL, but having some problems. The dates for some transactions in the register show as weird numbers (62/62/62), but then when you click on them, they go back to the correct date. Same thing with amounts; they show as "overflow" then change back to the correct number if I click on them. Both dates and numbers go back to the weird entry as soon as I click on another transaction. If I delete the transaction and add it on again, it seems to be fine so far.

Per the Intuit site this is a known problem and they are working on a fix, but it won't be made for that version, only the current versions.

I'm seeing the same problem with QuickBooks 2007 on a Mac Pro just upgraded to Snow Leopard. Deposits and withdrawals show as millions of dollars, dates are completely wrong and the overflow error shows up in numerical data fields. The data in the company file is fine, works normally when opened by QB on another drive with Leopard. Have you seen a solution or a posting by Intuit that explains what's going on?

here is a link....over 300 comments many about how poor the support is. Intuit is NOT going to support QB 2007.
