As well as the Watch window, are you aware of the excellent little
debugserver application (separate executable) written by Michael?
This lists messages from your application which you have inserted
manually using methods of the dbugintf unit,
such as SendMethodEnter(), Send MethodExit() and SendDebug().

The source is in a folder under /Lazarus/Tools, and the Readme.txt has
a stripped down example of actual use.

While you have to set up your application with specific code to send
appropriate debug messages, often in debugging you know roughly where
things are going belly-up, and a few judiciously placed lines of
SendDebug() code will pin-point what is going wrong. Which is far
more helpful for those of us who can't make use of the information in
the Assembly window!
