[Gambas-user] Release of Gambas 3 RC3. But I have a dream....

[Ru Vuott]

Hello Benoît,

well, I tried your "trick" on using file descriptors.

 It seems it's OK !

   But I verify a problem: when the midi-program runs, and midi events aren't sent, the use of one CPU springs up to 100% !!! If I press on a button or other object on the Form, the use of that CPU decreases to lower values. It is not important if these buttons activate some functions or commands: if I want decrease that 100% value of CPU, it enough I press a button for more times.

regards
Paolo
