you can set any location by just entering the desired numbers into the form. If this does not work for some reason what so ever you can also check for the file locations.lst (right next to your RayMan.exe. Right click that file and select open with, click any apps and hit "Editor". Now make a new line and enter your numbers just in the same style like the others above. Save that file and re-open RayMan. The new location will now be in the locations dropdown list.
I followed your instruction and added a new location in" locations.lst". The new location appeared in the locations dropdown list, but its longitude and the latitude changed.(Example: I entered 109.12,34.23 in the " locations.lst" and it become 109.7, 34.14 in the dropdown list)
Thank you so much for your reply. So, could you please tell me should I added a new location in" locations.lst" in decimal degrees? Or in hours and minutes degrees?
please add locations either - in the locations list in decimal degrees, or - in the locations box on the lower left of the RayMan main form in Degrees° Minutes' and Seconds"
