So I have an interesting little bug that has started happening on my new install of windows 7. I'm using an Acer Aspire 6920, I've got a mac keyboard plugged in, but the problem persists even on the Enter key of my Laptop, so I doubt it's the keyboard that's causing the issue. Any ideas what the problem might be? Edit: a restart fixes the problem, but is this a bug with the Windows 7 RC? What could I have done to trigger this?
