Yes, that is understood. One of its problems is that old versions were particularly badly coded, and won't obey any conventions or update.
It scrambles the forms we use for Classifieds and other inputs, and it can't do things it needs to do but does other things it shouldn't.
Shame really but that's the way it goes. Please try using a mobile browser and/or a mobile skin from the template chooser at the bottom left of every page (the spin box you can see there). Thanks.
