I have had an aggravating problem with TWS yesterday and today again, the applet seems to freeze for a few seconds I am not able to place an order, the mouse pointer shows as a double arrow and the hot keys no longer work. After playing around with the applet, resizing it, it gets back to normal but the problem always occurs at the worst time. What could be the cause of the problem? I have noticed that the applet is really slow when being minimized for a while I thought it could be a memory problem but I always keep about 40% of resources available when trading so it's strange.
When IB starts acting out for me, I take the simpleton approach, check that all positions are safe and restart it. This has definetly helped though some of my issues are my platform. Geo.
