OMG!
Thanks all of you for your valuable answers!! :D
I've just took hours (hours!) backing up my sh*t and making a great reset (Schwab style) to my computer, and installed Ubuntu 25.01.
After those hours, downloaded and installed sh3d 7-5 and....
It looks the same!!!
And the dialog open/save still looks when computers had green screens and pointers didn't exist. LOL.
Thanks sjb007 for your info. :(
Nothing else to do, just use sh3d with this ugly appearance and uncomfortable dialog.
Money talks.
