The pop-up blocker appears when I reserve or copy materials or apply for an inter-library loan.

* The screenshot is from Internet Explorer 9. The pop-up blocker appears in different locations depending on your browser and version. For details, see the help of the respective browser.
The pop-up screen is used for all applications from OPAC, such as for a reservation or ILL. Therefore, enable pop-ups by using the following method. (The descriptions apply to Internet Explorer 9.)
- Temporarily allowing the pop-up blocker
Click [Allow once] on the pop-up blocker notification bar.
(Depending on the browser version, select "Temporarily Allow Pop-ups.")
* However, with this method, if the browser is closed once, the pop-up blocker is enabled when the browser is started again. Consequently, the same work will need to be repeated to apply for a reservation or ILL in OPAC.
- Always allowing the pop-up blocker
Click "Always allow" from [Options for this site] on the pop-up blocker notification bar.
(Depending on the browser version, click the notification bar, and select "Always Allow Pop-ups from This Site.")

* Safari users are requested to go to Security in the browser settings menu to confirm that no check mark is entered in the "Block Pop-up Windows" check box.

After enabling pop-ups as described above, repeat the procedure for your application from the beginning.
