iScreensaver version 6.8.5 has a number of bugfixes and improvements, including fixes for several issues that could cause issues when running under macOS Ventura 13 (currently in beta, soon to be released) Authors distributing screensavers for macOS clients should update, re-build, and re-distribute their screensavers. Authors only supporting Windows clients can upgrade at their convenience.
Keyboard navigation with HUD enabled?
Does keyboard navigation work when the HUD is enabled? I know the HUD is enabled, because when I move the mouse it appears and I can control my slideshow with it. My understanding was if the HUD is enabled and I check the appropriate choices in the iScreensaver options for Enter/Return, space bar, and arrow keys that those keys will trigger the HUD and allow navigation as well, but they don't seem to be working on my Mac running Catalina.
