I have a solution with a couple different projects. I have been working on them and adding to them for several months. Out of nowhere, one of the subs in my project is not recognizing updated code. I had a for loop in there that was acting funny so I changed something and noticed no difference. I messed with it for a while and decided to just replace everything in that sub with a simple msgbox and it still tries to run the code that was previously there. I have built the solution, rebuilt it, cleaned it, closed and reopened it, removed the bin and obj folders and restarted my computer several times. This is not a server program or anything dealing with IIS or anything like that. Any idea what's going on?

**Edit**

Forgot to select my prefix. I am running Visual Studio 2010 on XP.
