Windows 7 Autorun.inf not working

[hsrstud]

On one of my USB drives I have an autorun.inf file that automatically starts a program when my thumb drive is inserted into my computer. After upgrading to Windows 7 the autorun.inf files doesn't appear to be working anymore. Has anyone else run into this issue? If so, is there another way to make the program (which is installed on the USB drive itself) autorun when I insert the drive?

Thanks for your help!
