"Blue dots" in left margin of source code don't line up while debugging

Hi Experts, I was doing some work on my app tonight and I don't know what happened but now a couple of my units (my app has 6 units) have blue dots at the left that don't "line up" with the code.... and it now makes debugging and stepping through practically impossible. Does anyone have any idea what I did and how to remedy it?

Thanks

Did you try rebuild all, or if that doesn't work delete all .dcu files and rebuild all?

Thank you guys, I will try those suggestions. Another thing I noticed - I use FastMM4 memory management module and the FastMM4.pas unit is included in my project... when I compile my project only *some* of the lines in the FastMM4.pas unit have the blue dots next to them - there are large chunks of code in that unit that don't have blue dots. I don't know if that could be a contributing factor... it's making me wonder, cause I'm also at the same time having  mysterious "memory leaks" problems...

Thanks

this usually happens after opening a file to a different folder in the ide

after that somehow it opens the file with the same name in that or an other folder

then those blue dots and code don't align correctly

Thank you all for the help - Sinisa, your link to the article did the trick! I had 2 units that didn't have blue dots matching with the final "end." statement of their unit. I simply deleted all the dcu files, copied over the contents of each offending unit to TextPad, saved that as a txt file. Closed it, then re-opened it in textpad, and replaced the old unit code with that. It fixed everything up for both units and the blue dots now match exactly! Thank you!
   I'm just wondering about the FastMM4.pas unit - the blue dot DOES match exactly with the final "end." statement of the unit, but there are many big gaps of code that don't have a blue dot at all... maybe that's normal for FastMM4?

Thanks!

the missing blue dots mean those pieces of code won't get called
the optimization of the compiler does this

> what's the point in compiling code which will never get used
