This topic was recently covered here:
As a general policy question, why was this thread closed so quickly? Why are threads closed at all? What's the use in being able to find a discussion covering a problem you are having if you can't join the discussion?
Regarding this problem, it seems that perhaps turning off real time quotes solves the problem. Although, for me, the issue only happens intermittently, i.e. if I get the bogus mutual fund update of $185.19 or similar, the price on the following day will often be correct. So turning off real-time quotes might stop the problem, or it might just be a return to normal quotes that one sees. My fix of course is to delete the bogus entry from the edit history file. I have over 10 such mutual funds which I need to edit every time this happens.
In any case, has the Quicken team been made aware of this problem? Whether it is caused by real time quotes, or not, I would like to see it get fixed.
Thanks,
