You can make AddressBand background and SearchBox background images with the dimensions you want and make sure they are TRUESIZE.
You will also have to change the Go Toolbar button images.
That's the only way I can see to change the sizes with WSB. I tried it and it is possible.
I found your post where you talked about it.
Since the latest Windows updates, it's wider, but nothing has changed in the theme.
How can I get an image with the correct size?
And is "TRUESIZE" an entry that needs to be modified ?
Do you have a screenshot of where to change the option ?
Thanks for your help.
