Setpoint widgets are not working for me

Hello,

I don’t know why, but setpoint widgets does not works for me in any sitemap. If it were only on my sitemaps, with my rules then I could think I made something wrong, but even the demo site is not working. Does anyone have an idea of what is happening?

Also, I have some problems with them being displayed in certain sitemaps, they look awful, like you can see on this screenshot :

Can you please give more information?
Which OS do you use (Server & Client), which browser, which Java version, which OH-Version?

Sure!
I’m using windows 7, chrome and Firefox browsers.
Java version is 1.8
OpenHab version 1.7 (the latest)
