Do they work well in the HTML5 module? If not they won't work in UWP as its HTML5 based.
Work perfectly in HTML5, and in iOS, Android and Windows.
I'll try the new beta that just post Yves and I tell you that I go.

We can't fix this, this is a bug from MS, they have confirmed it, so you / we have to wait for them to fix it. This doesn't happen only with apps created with Fusion, they simply don't send Key Up events sometimes. No workaround is possible, we tried.
UWP a great addition to the Builds and as long as you know how to work around a lot of the issues you can fix quite a few things without complaining too much. Very cool though.
