Hi Gerd et al, Downloaded 4865 and ran it to make a .GMAP with no changes to data nor options
Compared with running v4286 (which works for me so I still use) : MDR is now 43092K was 47347K Runtime (reading .MP files) seemed slower, maybe 30% slower Some .RGN files are bigger : now 5855K was 5823K, for example. Searching in Basecamp runs with no problems. Keep up the good work!
