I am having problems with some graphs not displaying entire histories. For instance:
GLD (picture attached), BCL (attached), NRF (attached).

And I have one stock that the history simply stops: PRWP (attached).

If I click the refresh button on PSM the charts go blank.

Thank you for your help.

I have the exact same problem.

With about a dozen tickers.

This is a big problem! Have had it for some 6 months now, with no resolution. Software bug....

I am new to this, and in my short time have had the same issue. Also I noticed the latest price information has not updated in my watch lists. From Friday July 23rd, some of the stocks are not updated. And when I do an update all, or update selected, it will not update.

Definitely a BIG bug in this program! Needs to be addressed by developer ASAP!!

This has been going on since at least April 2011
