invisible bars?

Ok, OK we will reveal the secret settings we used to allow a so-called "transparent" TLB!

First consider whatever desktop wallpaper you are using. It is either a picture or a simple colour. If you are using a simple colour then right-click on an empty space in the TLB and select TLB Settings...>Toolbar and check "Overwrite toolbar color". Next select "Toolbar color" and select the same colour as your simple colour desktop.

If you are using an image/picture for your desktop then take a screenshot of your desktop (with no TLB showing) using an image capture application like Irfanview and then crop the image to be the same as the part of the image under the TLB location. Save this image somewhere. Then in TLB Settings...>Toolbar>Overlay image select the image and you should be able to take it from there.

Any questions please post.
