Debug probe last evaluated code selection doesn't remain in history

edit

I evaluate a section of code in the debug probe and it executes in the current context as expected. However, when I press up cursor to repeat the last executed block of code in the history it's not there anymore! so I have to make a selection of the code and evaluate again. Which breaks my focus as I have to repeat that same selection may times in a debug task.

For a test, I do the same for a smaller section of the same code. When I press the up cursor it's there. I start to increase the size of the code block and when it reaches 24 lines it stops remaining in the history.

Is there a setting anywhere that controls the maximum size of the executed code that goes in to the history? or is this a limitation? I started a new project in case the project files where corrupted but it didn't make any difference.

I'm using winpro 7.2.9.0
