Helping people with computers... one answer at a time.

Sometimes, video drivers have issues that can manifest in this type of unwritten screen. We'll check for drivers and upgrades.

I have Windows Vista. And when I'm reading my email and scroll down, only half of the email moves. It only does this when it's not in full screen. This is not a web-based email like Gmail. If it isn't the mouse, I don't want to buy a new mouse. Can you please help?

In this excerpt from Answercast #60, I look at a computer with difficulties drawing the screen for an email program.

Email not scrolling

Well, fortunately I can pretty much tell you that you don't need a new mouse. It has nothing to do with the mouse at all.

What you haven't told me is exactly what email program it is.

Now in a case like this, two things come to mind.

Video Driver

One of all things is the video driver. Sometimes, video drivers have issues that can in fact manifest in this way. They are specific to the way a particular application might actually draw what you are trying to look at on the screen. Different applications do that in different ways; and as a result, different applications may only display this kind of a problem in certain conditions.

So, one of the first things that I would do is make sure that you have the latest video drivers for your specific video card and specific computer.

Typically, that means starting back with the computer manufacturer and seeing if they have any driver updates that would apply.

Software upgrades

Now, the other thing that comes to mind is in fact the email program itself.

Once again, you haven't told me what email program that is; but whatever it is, I'd also recommend you make sure you're running the latest version of that.

Obviously, the email program itself could have a bug and that bug could be manifesting only under certain situations: maybe only certain hardware that does what you've described - only scrolling half the window.

Like I said, it's less likely. My gut tells me it's probably more related to a video driver or a video card kind of issue. But while we're at it, it's a simple thing to do to make sure you're running the absolute latest version of the email program that you are using.

Finally, obviously in the interim (until this gets solved), if it doesn't do this when it's in full screen, you can continue to use your email without problem by putting it in this full-screen mode.
