I have a grid with 4 charts (multi-chart) of the same security. Each chart has two indicators. I have it linked (red cube at top right of the chart window) with the Quote Monitor window. I click on a symbol in the Quote Monitor and it populates the chart grid. Work great for the first 7 or 8 times I click on a symbol... then the next time, the charts stay blank.... says "loading". Sometime the charts eventually show up... or sometimes I have to log out/in. No exotic settings in the charts. IB tech support hasn't been able to help. I've tried several experiments to find the cause -- no luck. Please help if you know what might be wrong. Thanks!
