Cannot save breakpoints in 8.02

[leo4jc]

Hi I am new to Code::Blocks. I tried a simple hello world console application using gcc with -g.

My problem is: I can set breakpoints but these breakpoints are lost when I reload the project.

I look at the files in the folder, it seems like the breakpoints are not saved at all. Am I missing some steps to save breakpoints?

My version is 8.02.

Thanks,
leo.
