Measure tool missing

My measure tool is malfunctioning, as is my selection square in edit contour mode. I can hit the measure button and it seems to think its measuring since I can then also hit end measuring, but nothing shows up on the screen. My selection square also doesn’t show up but it does select everything that would be in the square if I try to use it. I have 2 versions loaded 7.1.35 and 7.1.20 and both of them are doing this which leads me to believe it is the computer. Anyone know what I should check?
