.CTX extension oddity

When a .ctx route is saved the .ctx extension isn't included.

You have to manually add it (in Windows, Tools > Folder Options... > View > UNCHECK, "Hide extensions for known file types".)

After adding .ctx to the end of the file name, when you ReCheck "Hide extensions for known file types" the extension is still visible.

All the above isn't the case with .GPX files
