Without seeing your code, it's very hard to guess.

The fact that window caption is color white rather than blue is usually an indicator that the focus is not on your app. But that usually is not enough to explain why the text for the various labels also turn to gray, unless you got a little fancy and also have an event handler to change colors for those labels depending on activation state.

It looks like you have set the Enabled property to false. You may have done it for the form itself, hence all the child controls appear disabled. I would expect that you'd know if you had done that in code, although it's not guaranteed, so it is probably set in the designer.
