Hi All, I've been continually impressed with this application. As with most of you, I'm an enthusiast when it comes to technology. When I installed Windows 10 Technical Preview, Sync was one of the first applications I installed. Sadly, after installation, it crashes when you try to open the app normally or while run under admin. Windows 10 was just released. I'm curious to know how soon the developers will be adding support for this technical preview. Thanks! Adam Just to clarify, it's crashing on 1.4.x. I just downgraded to 1.3.109 and that appears to be working fine. I'll just downgrade my other machines until 1.4.x is working properly.
