I am experiencing a recurring problem with OV, namely with data entry (especially when using Matrix). When I first load the system it seems to be ok in accepting data input, but as it sits for awhile it become harder and harder to data enter any trade information into the system, until I have to bang the keys over and over just to input a number, at the same its CPU usage grows to 25% of the processor's capacity, while it is doing absolutely nothing. I use TOS for my data feed. I talked to OV tech support and they suggested that I should try another keyboard, which I have - no change. I went through all my setting on the computer and disabled a few programs. (BTW I found that Intel Management and Security Local Management System in my Windows 8.1 is an absolute resource hog. It does not do anything useful and disabling it improves performance). I am still having the same OV problem. My system is Dell i5 processor and 8GB of memory. Does anybody have the same problems or idea? Any suggestion will be greatly appreciated. A general comment: I find using OV to be very frustrating, it seems like its technology has not evolved since the days of Windows 95.
