If "a dot" is the source of all your problems, you can easily solve this by placing a \strut instead of a dot at the top of the page. (Perhaps even \null would do.) \strut is an empty box with width zero and height of "one line" (generally speaking). I was confused for a long time since there are at least five different ways to achieve the desired results, each one with its advantages and drawbacks, so you may have to be even more specific about the layout. You can do the whole page with layers if you are sure that you want to provite all the coordinates by hand. If you use an alternative way (if you place a figure at the left or right side of text for example), space will be reserved and text will flow around the figure. If you place a figure in a layer, you'll have to manually adjust text width/height/hole, so that it won't overlap with the figure. Some alternatives to layers that come to my mind in the first moment are: 1. tables (http://wiki.contextgarden.net/Tables_Overview) with \bTABLE ... \eTABLE you can manully specify widths and heights of table cells and put photos in the left cell with specified width. The rest of data can go to the remaining cells on the right with automatically determined widths and heights. 2. grid typesetting http://pragma-ade.nl/general/manuals/details.pdf you can position the stuff on the grid (still precise, but in other units than centimeters) 3. http://wiki.contextgarden.net/Chromatograms uses \startpositioning ... \stoppositioning, which is probably something similar to layers. I never used it, but perhaps you can take a look if you find it useful. 4. many other ways for sure (depending on your needs), in worst case even plain TeX ;) > I discovered that the layers were "inserted" into the document via > "\setupbackgrounds[page]" so I understand why it acts like this but I > am asking if there is some way of getting layers working like I want? How is that? You can place layers in other ways than on the whole page (you can say that a layer has to be two centimeters from the bottom and three centimeters from the left edge or that it has to be 1cm wider than the text area of the page), you can put them in the backgrond or on the top of text, but you can't prevent them from being invisible to the rest of the page content (you can't place a layer and expect a text portion to flow around that layer). > Maybe I am going in completely wrong way?

You have a couple of examples in the official documentation (page 32 of details.pdf for example). google.com: "bleeding site:pragma-ade.com" If you position using frames, you can use negative values, yes.

Patrick already mentioned the new "search engine ;)" through articles. I often use google.com and "layers site:contextgarden.net" for example.
