Debugger doesn't highlight inside of some blocks
When running with GS/64 v3.3.2 and later 3.3.x versions, when using the GBS Debugger and stepping into certain blocks, highlighting of the current code being executed does not happen. Stepping is still occurring, you just can't tell where you are. When you step out of the block highlighting will resume. If you step-into a method, the new method is displayed and highlighting resumes until you return back to the original method.
This only happens for certain blocks (for example, a block associated with #do:). Other blocks (for example, a block associated with #timesRepeat:) will work properly.
