Yes with 1.4.0 the problem still ocurred, I did the changes in the 1.4.0 version, but before them the cpu usage were 100%. > The jiffies adjustment does not affect 1.4.0 anymore. I don't know much about dosemu implementation, so I don't know exactly what jiffies does, but my it changes INT2F_IDLE_USECS, INT15_IDLE_USECS and INT28_IDLE_USECS, since I used INT2F_IDLE_USECS in the usleep, I guess that it changes its behaviour. Now I see that I could had only divided INT2F_IDLE_USECS by 100 and would have the same effect... > 2. check_key_available has some code itself to make DOSEMU to become > idle.

I will make some more tests here with those information you sent, and will see what results I can get. After that, I will send the results to the list.
