Well using the task manager in windows, it’s
showing 94% cpu usage. Didn’t look at the memory though.

Memory leak repeatedly assigning new series to a chart. (2.0b1)
It ended up taking up the

issues with memory leaking, not CPU usage...
I'm interested if this is the same thing, or
something different?
