Button.Text property not updated in compiled executable

Hello folks,

Sometimes (including right now) when i change a property in my program, such as the text property
of buttons and labels, and i run the debug button in visual studio 2010 (.net 4.0), the text remains
unchanged.

button1.Text has been: "Test Credentials" for forever.

Now i want to change this property to "Test FTP Credentials".

In visual studio, everything looks and acts normal, but when i hit the debug button, the text is still: "Text Credentials"

I experienced this problem on other computers and visual studio versions as well, and am not
entirely sure of the cause, but i think maybe the executable or some parts of it, are cached somewhere, and not updated, but that is just a guess.

Does this sound familiar to anyone?
