Some parts of the GWISD web site require pop-ups. Press and hold the CTRL key while clicking a link that opens a pop-up on GWISD’s website. This will override Pop-Up Blocker just for that one click and allow any pop-up windows resulting from the click to appear. You will have to hold down the CTRL key before clicking the link every time you click on a link that is currently being blocked.
Or if you choose, you may choose to "always allow Pop-Ups from GWISD "in your Pop-Up Blocker. The steps for this vary depending on which Pop-Up Blocker you are using.
