Why is Opera not loading web pages right away?

My computer recently died, the power supply I think it was. But I used Opera on it, and it worked perfectly. Now I’m on a cheap $500 laptop untill I can get a new computer or power supply, and I just downloaded Opera on it. Now whenever i go to any page, it loads, but the page doesn’t show untill I refresh. So basically to see any page I have to type in the adress, or click on the link or whatever, wait for it to load, refresh, then wait for it to load again. Anyone know why this is happening?
