The title to this post is misleading. Why? Because Internet Explorer, while it does have its inherent flaws, doesn’t typically cause issues like this. What’s causing this issue is a toolbar. Queue the horror music! What you’ll come to find out about me is that I’m a browser minimalist, I can’t stand toolbars or unnecessary add-ons, extensions, etc.
I’m not going to get into the gory details of my overall hatred for toolbars in this post but I do plan on doing a more verbose article covering some different toolbars and the problems they pose.
Ok, back to the problem at hand. The user was complaining that every time she opened a new page in Internet Explorer 8, the zoom level was resetting to 100%. She needed it to stay at a default level of 150%. For those that aren’t aware you can set your default zoom level at the bottom right hand corner of the IE browser window (see below).
9 times out of 10 I find that for something like this a toolbar is to blame. In this case it was the Ask Toolbar. You can disable the toolbar but my suggestion is to uninstall it all together. I uninistalled the toolbar, restarted IE and the problem was resolved.
