Thank you for your responses to both of my problems. I will check on your suggestions.

Hi Running Opera 28.0.1750.48 on Vista. Weird problem I have noticed with Drudge Report and realclearpolitics. When I use the "Back" button to return to these pages sometimes it works fine but occasionally instead of text on the web pages all I see are lines. I haven't noticed this problem with other browsers and I haven't seen it with any web pages except for the ones I mentioned. Thanks for any ideas. I like the browser so far.

Hi thanks in advance to anyone who who has an idea. I just downloaded and started using Opera in place of Chrome a couple of weeks ago. I like the browser except for a couple of weird issues. I am running Vista. Opera version is 28.0.1750.48. My main problem is that Opera seems to go inactive or crashes if I leave it open without doing anything for a little while, like maybe 10 minutes. When I return the page won't scroll up and down anymore. Sometimes the bookmarks bar icons launch their preset sites and it begins scrolling again on a new page, sometimes the bookmarks bar icons are inactive. Sometimes the back or reload buttons work, opther times no. Finally, sometimes the close program X closes the program and other times I have to launch Task Manager to close the program. None of my other browsers exhibit this problem. After restarting Opera it works fine again until it sits inactive for a time again. Thanks for any ideas.
