performance slows to a halt after running for hours or overnight

[Wi!s0n]

I have grown to like NT8 over the last few months of using it, however there is an issue that encourages me to return to NT7.
After running NT8 for several hours or overnight, I've noticed a consistent lag in response to making any changes to an indicator to the degree the chart/program locks-up for 10-20 minutes or more while processing the change.
I'm running a fast PC, no 3rd party firewall and my connection is a cable broadband. I am using tick replay on most of my 8 charts. I don't connect to a data source until after the program starts and charts fill-in, otherwise the charts don't fill-in correctly if I connect automatically. Once I do connect to a data source my charts load reasonably quickly.
It's unlikely I'm the only user with this issue so is this a known issue with NT8 and if so what is the solution?

There are no inherent issues with leaving the platform running for several hours/overnight.
