I have a T500 Lenovo Thinkpad, Windows 7 Enterprise, 32bit, Service Pack 1.
When I hit Fn F6, it says "The camera is being used by another application".
It stopped working when the mother board was replaced ~4 weeks ago. The camera does work when booting from a Fedora live cd.
I tried the Microsoft driver, 6.1.7601.17514.
I also tried the Lenovo driver, 1.32.500.0 from Ricoh, dated 10/23/2009. It behaves the same with that driver.
How do I find out what application it thinks is using the camera?
