Hi,
intermario_gr i will try to resume what i´ve found;
In the Mdip 1.0 all the functions except 4 keys are touchscreen via preferences in the menu or in the star chart menu.
The only unsigned keys are the zoom in, zoom out, + stars, - stars.
The Mdip 2.0 is all touchscreen but the keymap is a mess... i´ve lost too many time trying to map the keys with Java adapter. I gave up and tried the 1.0 version at least the program works well (you can exit and search for stars on the contrary in the 2.0).
I dont know what expectations did you have but for a Java made 2 years ago this is very good in my opinion. There isnt nothing better not even paying that i´ve seen.
If you tic in the stars nothing happens because the search is in the menu. The star chart is just for guidance, that is the point.
If you want all functions in touchscreen be prepared to map the keys...and start with the 2.0 mdip.
Tip: In the "Help" you will find the keys.
