My Delphi XE is a bit crazy, there are some Units that persist in making the stops even after I remove the Breakpoint (F5) from the line, someone went through it and managed to solve it, already exclude the DCUs and recompilei and nothing. p>
What may have happened is that your IDE is set to not show Breakpoints, so ...
Press CTRL + ALT + B or go to the View-> Debug Window-> Breakpoints
This will display the list of Breakpoints that are configured. It will appear even the ones that are disabled.
It appears exactly below Event Log
.
If you do not see any Breakpoints, I recommend uninstalling the IDE and installing again.
