Need help with NetBeans

[coderX]

When I compile and run my project,it runs the older version of the project(as if no changes were made).I can see the changes that I've made in the GUI editor,but when I run it,older version of the program runs(yes,I did save and compile it before executing it).
The surprising bit is when I import the same project in different computers(all running win7,nb 7.1),some of them run the newer version while the others have the same problem.
Any suggestions?
