For some reason the Automatic Scene Preview doesn't work, even when it is set to "Auto Update", "High Priority", and "Preview quality>Fast". I have to keep clicking the bloody window for it to reflect any changes. The Preview window in the Material Editor doesn't update either, and again I have to click manually to reflect changes. I know this sounds lazy but it gets awkward when you have multiple windows open in the Editor and always having to click the window to see any changes.

I checked in the Preferences, and the only relevant option I found was in "Display>High priority scene preview" which was already ticked.

Vue5Inf is fully updated at this time....I'm guessing one of their "fixes" - like always - made things worse. I've only had Vue5Inf for about two months, so maybe they changed the whole Preview thing since 4.
