Parallels and New Devices
I love Parallels. It's probably one of (if not the) best pieces of software I've ever used. There is, however, an interesting bug that comes up when you plug a new USB device into your computer.
When you plug a USB device in, there is a popup that asks if you want the device to be connected to the VM or not. I don't really know why they have this option - I always say no, and the device is accessable to both OS's, but this popup is where the bug is visible.
I left Parallels and this popup running on my laptop, and before I knew it I my lap was being burnt by my laptop! The temperature of the computer had hit a rediculous 80oC. I opened activity monitor and saw that Parallels was using nearly 100% of the CPU (and had been doing so for the past half hour...)
Merely selecting "no" on the popup caused the CPU to drop to less than 2% and the temperature to go down to around 53oC. I dont know why this routine in Parallels requires so many CPU cycles, but someone should get to work fixing this.
