OK - Thanks to both of you for your help!

Thanks - after I posted, I checked both locations and found the variable in the location for 1.4. May I ask what the advantages of the (presumably newer) XML are?

Ah, thank you - but I do not know which XMLs I use. How can I find this out?

Hi all, I've just resized the small taskbar to occupy 24 pixels using the 10,10,4,4 contentmargins change. Now, I'd like to put a toolbar on this taskbar (an empty one to centre my icons) but the height of these toolbars seem fixed - they immediately cause the taskbar to resize to it's default size. If they're removed, the taskbar switches back to 24 px once again. Is there a way to change the height of these toolbars?
