[DUG]: Getting breakpoints working properly

[Dave . Jollie]

Hi, just moved to a new machine with XP (was on NT). Re-installed Delphi 6 and now breakpoints don't work! If I breakpoint a line (red dot), and then run the project, it's as though it runs a different version, as the "blue balls" don't appear in the source margin and the breakpoints never execute. (Breakpoints don't go the disabled colour either). the breakpoints are on obvious places that have to execute, like form create I've re-built the project a number of times, & blue balls appear, but go when I run the project and don't return. I've deleted all files except .pas, .dpr and .dfm, and rebuilt project - still no luck I've checked that the dll is being created in the directory I expect and that it definitely runs that dll (not another one created elsewhere) I've loaded another project and re-built, to see if all projects are effected - breakpoints didn't work on this one either   Are there some compiler, linker or debugger options, that must be on, in order for breakpoints to work? (they are at their default install settings at present)   Any ideas?   Thanks. Dave
