Problem with My Right Cross

This has started happening recently, and it's never been a problem until now:



When I punch a pad with my right hand (a cross) my wrist comes out of alignment and folds downwards. I have to really focus to make sure it doesn't happen.



I sometimes wear handwrap alternatives (the glove kind) but I have never worn handwraps before. It has only happened in the last two months.





Also, it doesn't hurt.
