You are right United thanks for the update its working for me now also......I spoke with NTEK's Apple Guru Mark Morris this morning this was his comments:

Chris,

Thank you for taking the time to download and try out UltraFlix for Windows 10

Really appreciate your feedback, having some difficulty reproducing the crash locally but you provided great info.

A new build will go out as soon as the problem is resolved.

Thanks again for taking the time to contact me with this issue.

Mark
