Thank you for your replys

I can't setup graphics before timer, because, the user of my program (in execution) can change screen resolution manually :/

This is my FreeBaic code :
http://www.freebasic.net/forum/viewtopic.php?f=4&t=23297

I use fb_isr_set, fb_isr_reset, fb_isr_get OF FREEBASIC
I think that Screen function is "relied" with this.
If I code my ISR timer with Djgpp in C, and compile in a .A library, and compile with my program who use Screen function, you think that this can work ?
I can test this tomorrow

Best regards
