I just upgraded from TWS 898.4 to TWS 899.7 per IB's Dav private message that the latest TWS revision has a fix to reduce the CPU usage. This reduced my CPU usage level due to the mouse movement over the tick line charts from 100% to a more acceptable level of 67%. I did this test on an older 1.7 GH single core CPU so I expect a much better performance when I install this TWS upgrade on faster dual core CPU.
Thanks IB Dav for you help with this problem fix as the IB tech support help on my current open ticket is obviously unaware of this fix.
