After messing with this software for several weeks i still have not found out how to do what i can do with any other software, namely starting from scratch, from a blank screen (or page).  I have experimented with about a dozen different templates, and even on the most simple one, after deleting all deletable objects i am still left with some whose properties (size, position, shape, fuction etc) i can not control.  Not only that, even when i try to overwrite these objects they restrict visibility and position of the newly created ones.  The attached file may help to illustrate.

The top part is a preview, the bottom the design view.  As can be seen the pale yellow object underlying the one i created on top of it, restricts the visibility of my own object in preview; essentially making the design process into a guessing game.  How can i get rid of it ?  Or is it really not possible to start from a blank page ?

Another question i have concerns how to retrieve previously asked questions and their potential answers.  Three times before i have posed qustions here, but the only time i reaped the benefit of the answers was when i left the browser tab on which i asked open for the rest of the day and returned to it later.  Is there not a better way ?

Thanks, René
