I am in the middle of a tight deadline and have had the pop-up screen for Parallels Update appear 4 times in 3.5 hrs. Its completely annoying. I have hit cancel and will wish to update at another time. NOT NOW, NOT IN AN HOUR. LATER! I have gone into Preferences, Update and have "once a month" selected. Why does it choose to remind me avery hour when i hit "cancel". Annoying!
I had the same problem and agree that if I cancel, I shouldn't get notified again for at least 24 hours. Also, it would be nice to have a button or link that takes me to a release notes page which could even be a forums post.
