In a previous post I had difficulty working out an issue due to the debugger (apparently) not line-stepping correctly. I have run into the same issue again.
My low level of skill with regards to this language means I need to be able to step through my code line by line in order to watch values changing; unfortunately the debugger doesn't seem to want to help me in achieving this.

It appears to skip portions of code, usually the bits I need to be examining.
Once again, is this something I haven't set up correctly?
