System controls if and how often PhotoLine checks for a new program version. The default setting is every 7 days.
Furthermore, on Windows you can control here, what to do on copying. If you want to use the data in another application, you should turn Write WMF to clipboard on. If you are only copying inside PhotoLine, you should turn it off, because this way copying is much faster.
Furthermore you can define what to do with data on the clipboard, when quitting PhotoLine. You have the choice between Destroy, Ask and Save.
There are three modes for pasting layers from the clipboard. The newly inserted layer can be centered in the window, it can keep its position, that is the position it had on copying, and its top, left corner can be placed at the mouse position. If there is already a layer at that position, you can define an offset for the new layer.
