hmm, that's a very old option, it doesn't really make sense to me...
I think, we should remove it.

the code switches off posmode, when clicked.
so it means "leave posmode", I guess...

you mean switching to posmode with mouseclick?
because in normal mode the map view is determined by the current position.

a drag function would be really nice, yes. but I think to do this properly 
some significant changes to the map handling code have to be done.

usually you should use gtk_button_new_with_mnemonic instead of 
gtk_button_new_with_label on buttons.
the same for the menus with gtk_menu_item_new_with_...

or you could add your shortcuts to key_pressed_cb in main_gui.c, this 
processes all key events in the main window.

the sf-svn list only sends out commit messages from the svn, nothing else.

bug reports should be added to the bugtracker on the sf-website. this would be 
the best way to track things, that can't be fixed very soon...
or reported to this list.

this is known. could be solved by using separate config variables for pda 
mode.

I'm currently working on the map code, i will have a look at it.

this means?

it works, but it does nothing ;-)

I think, this function could be removed completely.
or is there any use for it?

this can be removed.
maybe replaced by postgis db creation...
