I'm not very fluent in the tech stuff behind the computer, but this problem (if I correctly relate to it) seems to have been solved on my computer.
Started as a problem with my wife's computer hanging up that led to a search for a solution. The recommendation was to go to
Tools - - Internet Options - - Advanced , then uncheck the box for Enable 3rd party ext.
That solved her problem of getting an error message when Yahoo was trying to load on her computer. To see what, if anything, else may be affected, I made the same change on my computer and the result was I quit getting the jumping text.
A re-start is needed for it to take affect. And I can't say if it will solve your problem or cause a different problem. Seems to have helped mine so far, and haven't missed a thing to the best of my knowledge.
