Jeffrey, thank you for he help. I downloaded the your file, but it didn't solve the problem.
I did find out that the problem was related to the digital meter module using "automatic" sized fonts - when I changed the font size to "fixed" the lag problem went away. I only figured this out because I looked in the task manager when the lag was happening and found a process called "Usermode Font Driver Host" (fontdrvhost.exe) was using 6-10% of the cpu (which seemed like a lot). I'm running Windows 11 and I'm guessing that the new version of this driver host is glitchy when working with the digital meter module from DASYLab 2016. In case it helps: my laptop is using version 10.22000.832 of fontdrvhost.exe. Perhaps this can be fixed in newer versions of DASYLab (if it isn't already).
