I downloaded a project made with Delphi 2009,which is also what I use,however there is one breakpoint that I just can\'t remove.If I try to remove it,its being executed again af
View->Debug Windows->Breakpoints.
I'm very dissapointed at those articles.They explain how to add something,but not how to remove it.
Breakpoints are stored in the dsk file for your project. Close your project, delete that file, and re-open the project. All breakpoints should be gone. (Other window-layout customizations will be gone, too. You'll have to restore those preferences manually.)
If, for whatever reason, you can't turn these off in the IDE, as Rob says, this is persisted in the .dsk file.
You don't have to delete the file (and all of your other settings), though. you can just open it up in a text editor and find and edit the following section:
