How Often to Show Popup

"Show the Popup" combo box
Using this combo box you can determine how often the popup would show for every given visitor. This feature is based on the browser cookie capabilities, so if the visitor's browser has no cookie support or the cookies are disabled, the popup will show every time, no matter what option you choose from the combo box (see "Disable Popups for non-Cookie Browsers" checkbox below).

You may choose the popup to show every time, once only, once per session only (until the browser is closed), once per day and once per period. The latter option will let you enter the number of days in the field right below the combo box.

"Disable Popups for non-Cookie Browsers" checkbox
This option will ensure that your popup won't annoy those visitors who do not have cookies enabled or their browser does not support cookies. This is a very small group of users - most users have their cookies working. So, if check this checkbox, these visitors will see no popup at all rather than having the popup appear every time.
