Mouse Pointer Disappears over MathType 3.x Window
The information in this document applies to:
MathType 3.x (Win)
Some users of earlier versions of MathType find that their mouse pointer
disappears over the MathType window but it does appear elsewhere. Some
customers perceive the mouse pointer as going behind the MathType window.
The issue is that the video display driver is having trouble displaying the
mouse pointer over a 16-bit application, which MathType 3.5 and earlier are. This is why the mouse pointer returns when you move it back over any other
32-bit application, like Word 97 or the Windows desktop.
Our primary recommendation is to upgrade to MathType 4.0, which eliminates
this issue as a 32-bit application. If you have questions about pricing or
would like to upgrade to this version, you can do so by visiting our on-line
sales page. If you choose not to upgrade to this version, you may still be able to address
the problem so you may continue working with MathType. This will most
likely require downloading the latest video driver for your display adapter.

does not mean that you are using the latest drivers. In fact, for very new
models or video cards, they are more likely to have a new driver released for
If your computer is new or you installed a new video card, you are twice as
likely in need of updating your drivers. Computers that are put together
by companies like Dell, Gateway, Micron, etc. typically use the drivers that
come with the hardware that is installed. This does not take into account
the fact that drivers for new products are updated at a much higher rate then
older hardware. As a result, the drivers that are included with most new
computers are already out-of-date. Manufacturers of video cards make
available new drivers for free on their web sites to combat problems of this
nature. Make sure you are using the latest version for your adapter
by visiting your video card manufacturers web site.
The following procedure may be used to obtain your video card driver version
information. This procedure may vary from driver to driver and as a result
