I upgraded TWS from 898.4 to 899.7 on two unrelated computers and the account windows on both computers are screwed up as a result. The account window may or may not look correct (as I set it up) when I first open TWS provided I do not save the screwed up account window changes after the problem happens. The window can look correct but within a minute to an hour or more, the portfolio columns will change in their order, column width, and may have one or more new columns added. When I go back and check my global account window settings, the morphed column order will not match my global settings and the global settings may have also been altered by the bug to add one or more new columns. The altered columns are not readable due to the altered widths being unable to display the information. None of the column widths are retained. I can manually re-setup the portfolio columns and within a minute to an hour or more the columns will be all screwed up again. Re-setting up the account window and saving the settings does not fix the problem. It is like TWS 899.7 is determined to setup its own account window settings and override my settings. Anyone else having this problem with TWS 899.7?
