Same problem here, too. A 4 screen display appears: TOTAL VALUE, PORTFOLIO BY SECURITY, VALUE OVER TIME, and TOP MOVERS. Right click gives a menu — I've click all options but the register still will not appear.
@Richard Golden - I think your investment account for some reason has switched to the simple tracking method. To get it back to complete tracking method, go to the General tab in Account Details and then reselect "Complete-Positions and Transactions".
Also double check this setting in Edit→Preferences→Investments→Other preferences.
If you don't want new investment accounts to default to Simple Investment method, make sure that it is unchecked.
