Question 1999 C70 Convertible Windows Roll Down While Driving

I have a 1999 C70 convertible where all windows roll down by themselves while driving. To roll the windows back up the 'all windows' down selection has to be pressed. Only then will the windows roll back up. This happens more frequently in the afternoon then in the morning. So far we have checked the wiring harness in the drivers door, replaced the driver side window switch panel and even replaced a worn lock actuator on the drivers side. The windows rolling down seems to be correlated with changing direction and/or slight bumps in the road. Our repair person now believes that the computer might be defective and is suggesting an expensive replacement. Any ideas out there????

I am in England with a 2004 C70 convertible. When the ignition is in position 1 or 2 all 4 windows open. You can close them but very annoying. Did you find a solution?
