Hey guys

Having a very strange issue which I have started to notice when using the latest version of V7.5 data logger which is a little hard to explain ...
I start the data logger on the laptop , for the first 10 or so seconds it is "live" data, I can blip the throttle and get instant data changes on the screen.
The longer I log for , the more the data gets "delayed".

I got to a point that after logging for approx 4 minutes , I started getting a "data lag" of approx 1 minute ! - I can do a power run , 1 minute or so later the data comes up on the screen.
Immediately I thought I may have had too many channels or too many validated pids , so I started turning channels off, mind you these are pid/channel selections that I've been using with no issue for over 10 yrs ...this made NO difference.
Have I accidentally changed something in the configuration of the data logger or the V2 to cause this ?

I know Ross is gonna hate me , but this is on E38 ecu.
I'm using a HP core i5 laptop with win 10 which has never had this issue.
Anyone else strike this ?
