* harbour/source/debug/tbrwtext.prg
! declare HBDebugger as friend class of HBBrwText to avoid scope
errors when debugger code executes some protected messages.
It will be better to clean debugger code but I do not have
time for it now.
! use HBEditor() in edit mode to eliminate problems with cursor
positioning in source code window
* harbour/source/debug/debugger.prg
* added protection against RT error during macro evaluation of wrong
user expressions
