I am not sure why this was moved...
I run Vista on my Gateway laptop. dual 64Might be a good reason to move it to the Windows Software>BaseCamp forum.
I have 1:25000 topos of all of France, I can only see these in Basecamp from the device so it must be connected. Is there a way to install these topos on the PC itself? I am guessing the snail performance is justified if Basecamp has to go to the device.
