Hi,
I thought Desktask would freeze upon reading data from Outlook, not after reading the data and then having some activity.
I'm running DeskTask right now, he already read data from Outlook and CPU is 0% and occupies around 5MB of memory.
It's the first time time I heard of such behavior of DeskTask running. Most reports are related to issues reading the data from Outlook.
There is absolutely no spyware nor anything strange in any of my programs, this can be confirmed by the 100% free certification from softpedia.com, besides I have a lot more to do then write code to spy on other people's computers, believe me.
So in you case I don't know what is the problem, but definitely there is some sort of problem in your Windows System, But I would not recommend a full reinstall of windows, try disabling programs like Anti-Virus and stuff like that to see if it improves DeskTask idle time.
Thanks,
