watches dialog now without DoInitDebugger
Revision 1.5 2003/05/18 10:42:58 mattias
implemented deleting empty submenus
Revision 1.4 2002/05/30 22:45:57 lazarus

Revision 1.3 2002/05/30 21:53:56 lazarus
MG: fixed form streaming of not direct TForm descendents
Revision 1.2 2002/05/10 06:57:48 lazarus
MG: updated licenses
Revision 1.1 2002/04/24 20:42:29 lazarus
MWE:
+ Added watches
* Updated watches and watchproperty dialog to load as resource
= renamed debugger resource files from *.lrc to *.lrs
* Temporary fixed language problems on GDB (bug #508)
* Made Debugmanager dialog handling more generic
