I managed to install MapSource 6.12.4 from the CD using Wine 0.9.59 under Ubuntu 8.04. I could configure the unlock code, see maps, etc and connect to my Zumo 550 to download data OK. The problem is running the update package, MapSource 6.13.7. It executes until the opening screen ("Welcome to MapSource Web Update") and then just sits there. There are no buttons or input boxes anywhere on the window. If I run it with Wine debugging turned on I can see mouse and keyboard activity, but I cannot tell where the app is hung or what it's waiting for. Any suggestions? TIA Tom
