I have attempted to contact you for some time, asking when you are going to enable Handycafe to run on Windows 10. Surely you know that Microsoft has made upgrading to Windows 10 free for existing Windows 7 & 8 license holders, and all of the PCs in my cyber cafe are eligible. I would like to do so, but must await your enabling of Handycafe for Windows 10.
It's impossible to say when the new version will come out for Windows 10. I have checked their website, but there is no specified information about Windows 10 update. There is also a contact form which is provided in case you have issues, but that seems to be the only way to contact the developers.
