If you use Choralplayer without an “ads-stop” code, it is possibile that the so-called “popunder” advertisements are displayed, and they show up on top of the Choralplayer tab. Therefore, the Choralplayer tab remains hidden until one selects the Choralplayer tab again, or closes the advertisement tab.

When accessing from a computer one can select the Choralplayer tab again, or close the advertisement tab, very easily. This is an example on Google Chrome:

In the example above, the advertisement tab shows the label named “Download” (this is just an example), and it is displayed on top of two tabs, which are partially hidden by it: on the very left side there is a tab from the Choralia website; then, between the first tab on the left and the advertisement tab, there is the Choralplayer tab.

To select the Choralplayer tab again you have just to click on the tab with the Choralplayer label. The Choralplayer tab will be moved on top so that you can use it and listen to music normally. Alternatively, you can close the advertisement tab (“Download” or whatever is the name of the advertisement tab in your case) by clicking on on the “X” mark highlighted by the arrow above. The Choralplayer tab will be displayed again on top after closing the advertisement tab. If other advertisement tabs show up, the operation of selecting again the Choralplayer tab or closing the advertisement tab will have to be repeated.

Managing tabs on a mobile phone may be a little bit more difficult because one may have to first activate a command that displays the various tabs that are open. For example, on an iPhone the procedure to identify and select or close the various tabs that are open is described in this article:

This is probably the most important section of the article above:

On other mobile phones and browsers the procedure is similar: you have identify and activate the command that displays the various tabs that are open, and then select the Choralplayer tab again, or close the advertisement tab. As an example, if you use Google Chrome under Android the number of tabs currently open is displayed in the small box highlighted in the following picture:

If you tap on that box, the various tabs currently open are displayed, and you can the select the desired one, and/or close those that are unnecessary.

By doing so, you should be able to easily use Choralplayer also in the case “popunder” advertisements are displayed.
