brenaa said Hi all, I work on U9.3; a PC with W10 does not display labels (other PCs work properly) ... Suggestions or solutions? Thank you Alessandro  

Have you tried a newer version of Uniface that supports Windows 10? From memory, we had to do work specifically for Windows 10, and you are using a version of Uniface that was not verified for Windows 8.1, yet alone Windows 10.

Not yet because it is forecast in the coming months. Anyway, all PCs are with W10 and only one has the problem

Something different like a service pack, browsers update? Could be an OS resource file that is different and causing it. 

I will check it as soon as possible, thank you
