Now that the final build of Windows 8 RTM has been released, DisplayFusion 4.1 and higher will be developed against the Windows 8 RTM build. Unfortunately, some issues may show up in the Windows 8 Release Preview because of the changes we've made for Windows 8 RTM.
We'll keep this topic up-to-date with known issues in the Release Preview, but if you're still using the Release Preview and you notice an issue that's not on this list, please let us know by creating a new Discussions topic!
