I installed the latest perfmon on a new windows 7 64 bit machine. Looks great and does what I want (fixed scale network graph would be good...) but...
with perfmon running the screensaver and machine sleep never kicks in. If I stop perfmon everything works. start it up again and the machine stays awake.
It appears quite strange to me; I've been using Perfmon for many years but it hasn't had any problem or incompatibilities with screensavers. I'll try it in my Win7 test machine.
Just a heads up. This also happens to me. When Performance Monitor is running, my Win 7 64 doesn't run screen saver, turn off monitor or go into sleep mode. Something in it is tricking the OS into thinking there is screen activity. Anyway, nice app - very well written and useful. Thanks.
