We have identified some issues that arise which can prevent screensavers and the editor software (Designer) from working if a user upgrades to macOS Big Sur 11.5 or the beta version of Monterey (12.0). We have found the problem and are working on a new version of iScreensaver Designer which will remedy these problems. This will require that you re-build and re-distribute your screensavers. We will have another annoucement soon. ---

Please note that macOS Monterey has a number of issues, including video playback problems, where movies may get stuck on a certain frame, or play back invisibly. We have identified these as bugs in macOS / WebKit and are hopeful that Apple will fix them before official release. In the mean time, we have a new version, 6.8.1 which adds fixes and/or improvements for some of these issues on macOS Monterey.
