Hi again
this time
1. downloading the .tar for linux in Virtualbox and
2. running the installer that is in the QB64 folder (1,2) after extracting it by Software managment of Lubunt
after a while of time it works!
Yes QB64 1.3 appears on the screen of lubuntu!
WOW tonight it is ok for QB64!
about your questions
here screenshot of troubles and results..
on running
1. there is a problem with a font
but going on
2. the interface appears to be too large for screen!
3. the window of program doesn't draw adjourning itself while I drag it on the lubuntu's screen
4. each time that I click on a button I get 3 times the error of wrong handle of Font because I trig the draw adjourment of the window of the program
5. you dialog box works fine both as aspect both with dragging it in the main window of the program
now you must wait for direct user of Linux, not in Virtualbox.
Goodnight for me and for all need to sleep.
