It happens randomy, sometimes when requesting a new ticker, sometimes when changind some simple configuration, etc, the only way to get around this is to REBOOT TWS completely, a major pain, anyone have similar problems? more importantly any solutions???
this has happened with the last 5 or 6 TWS releases, both beta and full release.
