I have finally found Navigator is the GPS I like most. I have just one problem. During navigation, if ign switched off (say at a fuel stop) my Windows 7 system goes to sleep, when ign on, the navigation continues fine, but the info panels (next turn, road name, ETA, etc) are missing. I have to shut Navigator, re-open, and re-enter destination to get them back. I have set allow sleep to 'yes' in default_settings. Any suggestions?
