The cost of new features ...
You are right about the different behaviour in BW8. The "Update Only When Shift Key Depressed" setting does not affect Browse synching in BW8.
But the folks at BW added a new feature in BW9, the "Sync Browser on Mouse Change" setting. This new feature is occasionally useful, and on the one occasion that I used it, it was handy to have the "Update Only When ..." setting, to keep the browse window from wildly fluctuating.
Seems to me that since the two modes of synching (Mouse Change based and Verse Change based) are useful in different situations, it would be nice to have Verse Change synching independent of the "Update Only When ..." setting, while retaining that dependance for the Mouse Change synching.
When I first used "Mouse Change" synching I assumed that it was either/or between Mouse and Verse, since they have such different uses; it may be easier to separate their functionality if it were changed to either/or.
(By the way, I did notice the synch problem, but didn't pursue it.)
Synching: Browse tab, Browser Window, Search Window tabs
I'm reviving this thread to report on what I'm currently seeing in BW 9.0.007p.1 (SH). I have the option Update Only When Shift Key Depressed on the Analysis tab in the Analysis Window unchecked, and in the Browse tab Options button I have selected Synch Browser on Verse Change, Synch Browser on Mouse Change, and Tab Display Versions Mirror Main Browser Versions. I have the Browse tab in the Analysis Window set to Single Version mode, and the main Browser Window set to Multiple-Version mode. The verse displayed in the Browse tab in the Analysis Window synchs with the verse in the main Browser Window when the latter verse is changed by means of the Command Line, the drop-down verse selector, or the "spin" up and down arrows in the main Browser Window.
However, the verse displayed in the Browse tab in the Analysis Window does not update/synch with the verse in the main Browser Window when I switch to a different tab in the Search Window. For instance, I'm comparing the versions of the cleansing of the temple in Mark and in John. (This is not the only BW tool I'm using to do this, but bear with me while I focus on this one.) In tab 2 in the Search Window I have Mark 11:15 displayed in Multiple-Version mode in the Browser window, and Mark 11:15 and following appears in Single-Version mode in the Browse tab in the Analysis window. In tab 3 I have John 2:13 displayed in Multiple-Version mode in the Browser window, but when I switch from tab 2 to tab 3, Mark 11:15 and following still appears in Single-Version mode in the Browse tab in the Analysis window. I can use the Command Line, drop-down verse selector, or "spin" arrows to change the verse in the Browser Window, and then the Browse tab updates/synchs to it, displaying verses in John 2. I can also click the Browse Window Options button in the Browse tab and select Synch With Main Browser Verse Now to accomplish this. But of course if I do this with tab 3 and then go back to tab 2 in the Search Window, I get Mark 11:15 in the Browser Window while John 2:13 and following remains in the Browse tab. This holds true whether or not I have the Analysis Window split into two columns.
I hope that's clear. I can attach screenshots if it's not. My question is, why won't the Browse tab in the Analysis window automatically update/synch with the verse being displayed in the main Browser Window when I switch tabs in the Search Window? It seems like that's the whole point of being able to have Single-Version mode in the Browse tab and Multiple-Version mode in the Browser Window. I assume that BW 9 is working the way it's intended, but this seems like a feature that could definitely be improved.
