title: How to step into RTL/VCL?
body: <p>When debugging using the Delphi 7 IDE how can I step into code in the program files/borland/delphi7/source folder? </p>
  
  <p>Sounds like a dumb question, but inquiring minds want to debug.  (not that I think anything is wrong with the source, I just want to know why for the 9000th time I can't assign a TJpegImage to a TjpegImage).</p>
