Autolock

Hi
It seems that the autolock of the device (N95) causes troubles while my application is on the background.
It sometimes gives Kern-Exec 3 when unlocking the device and sometimes ehwn receiving calls while device is locked.

I would appriciate any information & ideas about possible events which might occur when device goes to autolock\unlock mode which could cause these unexpected problems and ofcourse if there is any known ways to handle this.

Thank you very much
