Tests on vBulletin 373 PL1, Fresh Installation (No other Mod on the Board):

Test 1:

When Maximum Visible Posts Set to Zero (0), (Maximum Displayed Posts Before Page Split if 15), I started Having Eight (8) Posts on the Page, and from New Post Number 1 the Warning Title on Top Appeared ("he maximum amount of posts on this page can display has been reached..."), as mentioned on previous Posts this Setting to Zero (0) is Not Working Well Deactivating the Checkings; the moment I Posted New Post Number 10, the Bug Triggered, Stopping Hiding Old Posts and De-Activating the Quick Reply for the User that Posted Post Number TEN (10), after that His Posts didn'r Show on His Page and Old Posts don't Hide.

Test 2:

I Set the Maximum Visible Posts to 17, (Maximum Displayed Posts Before Page Split if 15), I started Posting Messages Until Completing Post Number 17, after that I Counted FIVE (5) New Posts until when on Post Number SIX (6) the Bug Triggered and the Quick Reply Asked Again to Click on a Post to Activate and the Mod Stopped Hiding Old Posts.

Test 3:

I Set the Maximum Visible Posts to 7, (Maximum Displayed Posts Before Page Split if 15), I started with 3 Posts on the Page and Posted the First 4 New Posts to Activate the Hiding of the Posts from there on, After that when I Posted the Fifth (5) Post over the 7 Allowed per Page, (4 Posts Got Hidden), then for that User who Posted New Post Number 5 (over the 7), the Bug Triggered, the Quick Reply Got De-Activated, the Old Posts Stopped Hidding, and His Replies didn't Showed on His Page but Yes on the other Users's Page.

I made this Tests with Google Chrome for One User and FireFox for the Other, simulating the 2 Windows for the 2 Users.

(The Bug Happens No Matter the Number Set for "Maximum Displayed Posts Before Page Split" on the vBulletin Options., on my previous Post I had this Setting to 10 and on this other 3 Tests I set it to 15 as mentioned).

I Hope this 3 Tests and it's Results can Help You on the Solution of this Bug, Coders Shack.

My Best Regards.
