I noticed this a few days ago. For instance, when editing a generated media text event and I want to change the text color, the color selector screen comes up behind the text screen making it impossible to choose a color. When rendering using Vegas to Hanbrake, the Handbrake screen comes up behind Vegas; I have to shrink the vegas window to see Handbrake. I can find no preference in Vegas to choose or remove the Vegas on top always behavior. I suspect I've changed something in Windows 10...I was diddling about trying to correct some other issues a couple of weeks ago. The behavior is very inconvenient. Thanks for any suggestions that will restore normal behavior for Vegas Pro.
