Maybe a thread talking about bugs from previous versions not fixed in Quicken 2008 will help people make purchasing decision. So, I'll start it off with one I just noticed, myself.
From what I see from Google, it looks like it's been around since at least Q04 and possibly Q03. Quicken seems to randomly blank out the Maturity Date of CDs in the Security List and list them as 0/0/1900 in the Alerts Center. Plus, there doesn't seem to be a way to delete these old Maturity Date alerts. The specifics on my situation:
In the Alerts Center, the Show All tab only lists these type of alerts for the period set on the Set Up tab (Investing | Maturity Date | Keep The Alert In The List For). On the Set Up tab, I have 30 such alerts showing (alphabetical by Security Name with no way to sort by Maturity Date). Only
7 of those are still active. The other 23 alerts are expired. Whether or not I delete alerts from the Show All tab or just leave them to fall off as their alert periods expire, the actual alerts don't seem to get removed from the Set Up tab. I've even changed the Maturity Dates to blank for some of them in the Security List and they still show up on the Set Up tab with their original, expired, Maturity Dates. Well, at least until I click on that alert, at which point Q08 faults and ends. When I return, the Maturity Date in the Set Up tab is set to 0/0/1900. That Set Up tab currently shows 10 securities with that same 0/0/1900 date. I changed them to their proper dates in the Security List and they seemed to be correct (though expired) in the Alerts Center. But, after exiting and restarting Quicken, a random set of them were reset back to 0/0/1900.
