SSIS Package Crashes Application When Entering a Data Flow Task

I noticed my SSIS project crashes when I enter a Data Flow Task.  I have 3 different DFT it crashes on.  All 3 DFT have a significant amount of complexity.  I installed VS 2008 Service Pack 1 and that did not solve my problem.  The only time I was able to get into the DFT without crashing is when I've previous crashed and after restarting it asked to recover packages.  Any ideas on how to fix the problem?
