This is really weird. Out of frustration I moved a SSIS package into the old development environment and did my debugging. I then moved the package back into the new environment, but I forgot to remove my breakpoints. I then executed the package and it stops at the breakpoints. I cannot work this out.
For the past three weeks I have not been able to step through my script components. Being a small company I'm sure nothing else has changed, otherwise I would have heard about it.
