When I first bought this app, I was pleased for the most part with its functionality. It offered several tangible advantages over Spaces. However, I reported an issue that the support team said they aware of and working on, but it never got fixed. In fact, the only update that came out at all for this app in, I think, the last two years, was this beta release. Now, the developer's website basically states that Desktops will never be compatible with Snow Leopard. What did I pay for exactly? I think You Software treats their customers very badly, and I would never send them another penny.
