[Update - October 28 Apple seeded the final version of Leopard to developers late on Friday. We have been doing compatibility testing through the weekend and are aware of a couple of problems that are being investigated. There is a general problem with assigning hot keys in the menus across the product line. We are investigating this and hope to have a fix shortly.]

With the arrival of Leopard (Mac OS 10.5), we thought it would be a good time to update you on the status of compatibility of our products with the new operating system. The short (and sweet) answer is that, in general, everything works pretty well. There are a couple of caveats, so read on to see the specifics for each product.
Note that all of the testing we have been doing has been with developer preview seeds that Apple periodically distributes to third-party developers. To date we (and other independent software companies) have not received the official GM build of Leopard, so there is always the possibility that Apple has made some last minute change that could cause a problem.
If you have encounter any problems using our applications on Leopard, please send us an email. We are committed to addressing any issues that might crop us as quickly as possible.

You Control works fine in Leopard, with the exception of two modules, Fast User Switching and Calendar. Leopard has completely redone how it handles iCal events and to dos, so much of the Calendar module is being rewritten to support this. Look for an update to You Control to be released this fall with this functionality.

You Control: Desktops works well under Leopard. As you may be aware, Apple has introduced Spaces in Leopard; this is a virtual desktops application that is basically a simpler version of You Control: Desktops. We think most of you will prefer the configurability and power user features that come with You Control: Desktops.
Note that we currently do not support running Spaces and You Control: Desktops simultaneously, so when you run You Control: Desktops, make sure Spaces is disabled first.

Everything appears to work fine in You Control: Fonts on Leopard.

We have seen no compatibility issues with You Control: Tunes in our testing on Leopard.
[Update - October 28 Unrated stars in the menu bar have a white background; we will fix this in an upcoming update.]
