Hi Richard,

Sometimes SSIS message boxes "hide". They will appear in the task bar but, although modal in every other sense, will not appear on top of the other forms. Another possibility is you are executing the package with the package MaximumConcurrentExecutables property set to 1. The default is -1 and translates to "Run a number of tasks at the same time that match my CPU count + 2." If you have a single-core machine, SSIS will execute 3 tasks concurrently when MaximumConcurrentExecutables is set to -1; if you have 8 CPUs, it will execute 10.

Hope this helps,

Andy
