Hello. I have noticed a curiosity when I am running Pharo 8 on Windows 10. I am in the habit of leaving the Task Manager open when I am working, and it seems that Pharo 8 is using the CPU when I am doing nothing. When the image - which is exactly as first loaded, with only the welcome window visible - is loaded, CPU consumption is zero. I open a playground, get a list of recent files from the playground cache, open one of the files but do nothing with it; the CPU activity is constantly changing within the range 2.5% - 3.5%. After 5 mins of no Pharo activity by me, the CPU is still in the same range. I reloaded an earlier image, which is Moose Suite 6.1 (Pharo 6) and opened a playground in the same way. After a few seconds, the CPU usage dropped to zero. This activity is a feature of the newest versions only. It's obviously not a major problem, but I would like to know, if just out of curiosity. Thanks for any help.
