Zooming works correctly, but the box in the centre of the screen remains. What is presented there is zoomed, but the size of the box remains half the screen size.
In the mean time I discovered that the content of TOPOGB2.tdb (125 KB) causes the problem. I had an old version of Topo Great Britain and I used the old PRODUCT.tdb (41 KB) by copying it to the TOPOGB2 folder and renaming it to TOPOGB2.tdb
Now the problem is over and everything seems to work correctly (I didn't test it extensively).
I also removed [HKEY_LOCAL_MACHINE\SOFTWARE\Garmin\MapSource\Families\TOPO Great Britain v2\1\Logos] and all its subdirectories from the registry. Now the osgb.gif image isn't displayed at start-up of the Topo Great Britain.
