Hi, just installed Windows 7 RC Build 1700 English 64bit. I have some quite old bluetooth usb stick (CSR Bluetooth Radio, CSR plc) and a Microsoft Wireless Intellimouse Explorer for Bluetooth. In the Windows 7 Beta the mouse was working OK. In RC the mouse is found as a device and drivers are installed successfully. BUT: Once the driver installation is finished the mouse will never work, meaning if I move the mouse nothing happens. Any ideas? Cheerz, Hannes.
