Machine specs:- Intel i5 Quad Core. 8GB Ram. 128GB SSD main drive running Win 7. I am running a trading platform on the above machine, with little else running apart from security stuff. When running just 1 chart or 20 charts the CPU usage is 10-20% and Ram stays about 50% used. Problem is mouse cursor freezes or lags behind mouse movement by an unusable amount - a question of ~5 second between moving mouse and cursor following. Same with clicking on an icon - big delay between click and action. There do not appear to be any spikes in either CPU usage or RAM, so the figures above should be a good guide. All other software is running well, with no delays, so this particular platform seems to be the problem, but as it is important to me, I would like to find a solution. Any help appreciated.
