title: Control events not firing after ASP.NET 3.5 conversion
body: <p>My department is currently converting all of our projects from 2.0 to 3.5, and we are experiencing an odd side effect.  It seems that most, if not all, control events aren't firing after we convert the projects to the 3.5 framework.  At least not initially.  Case in point, I was looking at one of our internal interfaces that had been converted, and none of the button click events of drop-down selected index changed events were firing.  I moved on to something else unrelated then went back to the page approximately 2 hours later, and then the events were firing.</p>
  
  <p>I've loaded the .aspx page in Design mode and ensured that the events were tied properly to the code-behind methods, and some projects still don't respond to events.</p>
  
  <p>Has anyone experienced this?  I've done some searching on the web and have not been able to find any relevant answers.  Any information would be greatly appreciated!</p>
