Sorry for my bad English first. I use keil 7.0 and I wrote a little RTX program, and I have a question: When I STEP debug task 0, it just run in task 0 not run to other task, but at the time, other tasks is still running. I try this program at other software ( use keil Compiler 6.0), it could running well, when I debug, it setp from one task to another. I think it maybe my problem, such as I have a correct configuration. What can I do now? Thanks a lot. Jun Liu
