I created a prototype of a website, and I cannot understand why a button I created disappear when hovered.
The different states of the button all exists, and I have not this problem with other buttons, or with the same button in another page (this one is in the master page, but other are there too and they behave correctly)
This happens both in the preview pane and the html prototype (the 2 I've checked)
It's been copied from one page to another but - can it be the matter? States and all the rest seems ok.
