So for a month or two now, my windows explorer will say that it has stopped working, and restart. Recently, I realized that it happened only when i scrolled the cursor over the right side of the start bar (I have the spiffy windows 7 style on, so it happens right on the border where it goes from quick program start icons to lenovo wireless display, lenovo keyboard settings, lenovo toolbar, lenovo battery level, lenovo charging icon, standard battery/charging icon, standard wireless display and volume setting, and clock/date). So basically, it doesn't occur when i click on the google chrome button to bring up my web browser, but it does if i click on volume or wireless settings in the bottom right corner.
