I added some Notecaddy express definitions and put them on a custom popup. Since then I have been getting a lot of lag when trying to look at pop ups. Enough that I've missed out on several potential opportunities due to being unable to assess the situation properly. I'm not sure if the Notecaddy definitions I made and new pop up were the trigger for this, but that's when it started happening.
My PC should not be a bottleneck here, Threadripper 1950x with 64gb RAM and overclocked a little.
