Yes, been those routs thanks chaps. Task-bar will broaden, and the icons will even reach a single column - but when I swipe it down again, it stops at two rows thick.
Odly, the start button seems to be taking up that double height as well, despite the quick launch icons being set small and taking a normal single row.
In addition to this, the open browsers are displayed on the task-bar - UNDER the quick launch items. Don't recall this being the case, but I've got nowt to compare it with unless I ask the Rivetess in TX.
However, closing the browser and losing that FF emblem and label still doesn't allow the task-bar to go to one line.
FF - Tools - Options all looks normal.
View, can't see anything here either.
Start - Properties. Nothing there leaping out at me.
It's been like this for months, and just annoyed me one too many times, but unless any light-bulbs come on over heads, better get back to the old tome - time is running out.
EDIT Strange, but there doesn't seem to be any bar to the left of the Notification Area. (The faint lines that can be pulled to stretch it. ) I'm not hiding any items.
