The best thing to do is distill things into a simple application (as
possible) and make steps which break it consistently. Then, with that in
place you can set customized breakpoints and drill in effectively.

Walking with F7 forever is an indication you are depriving yourself of
Delphi's awesome debugging capabilities.

From the hip, your problem is most likely doe to a missing KeyLinks
situation.
