Good to know you're successful!

Here's another thing that doesn't work as I expect:

While in VS, with my Master package in focus, I hit Ctrl-F5. VS does a build then executes the project from that package. Now, due a problem in one of the packages, execution fails. I go to the offending package, fix the problem, return to the master package then hit Ctrl-F5 again. The build fails! Why? Because when VS invoked dtexec.exe and the one package failed, dtexec did not terminate. I have to go to task manager and kill it.

Kinda counter-intuitive!
