Ah, the joys of confusion ....

we are talking about the same button and yes, it takes me back to main window. However, that is OK because of what I see in the map dialog.

I think it best to start afresh with getting a map loaded and that we check that we both see the same things ... or not.

1) Geotiff in ../MyDocs/MyMaps.
2) start qkandkartem and press "menu" button
3) will open up a dialog, which one depends on previous use. Separate left and right arrows at bottom scroll between dialogs and there is a map button to take you back to the main window. Dialogs present rae "About" , "GPS", "Waypoint", "Track" and "Map".
4) The map dialog has a "rebuild database" button. If the file name of your .tif placed in .../MyMaps does not appear there after rebuilding the database then it is of the wrong format I would assume. important point is that it must be there if qlandkartem is to display a map.
5) Pressing "map" button in map dialog take you back to main window.
6) Map will appear if it falls within the zoom area of the current location (as I wrote in post above) or if you scroll the main window to the map area.

I hope that is clearer. If no file name appears then there is a problem with the geotif and you will not see anything. If the geotif name appears you should see the image provided the coordinates of the main window derived from the GPS are within the map bounds. I am unsure if there is a file size limit for the geotifs.
