Ever since I bought my new laptop, Whenever I add a text (In Vegas 14 & 15), everything works fine except the live preview on the preview screen which makes it hard for me to re-position/resize my text according to my screen.. I can only see the changes after I exit the Text Editing Tab, which is kinda annoying.. This never happened on my old crappy laptop and I couldn't find solutions anywhere.. Can anyone please help me!?

Thanks!!....
