Google Maps does not show in windows XP

[routeconverter]

This is really a problem of my PC.

Looks like that.

It is no longer possible to exit Routeconverter.
I need to hit "Ctrl+Alt+Del" to stop the task.
It seems it is a Java error.

I would not second that, it's more likely a problem of your PC or a problem I didn't understand yet.

I disintalled Java. I manually deleted the java directory. I cleaned the register. But the problem is still there.

Which excludes Java for me from the list of likely problem sources.
