I have an odd intermittent problem where with a few programs, sometimes there are areas within the window which are unresponsive to right or left mouse clicks whether from the touchpad or bluetooth/wired mice. hovering over a particular spot brings up mouseovers etc, but clicking or scrolling produces nothing. For instance, I often open Internet Explorer and do a Google search and I can click on a few of the entries but not all of them, and I cannot scroll the page even by trying to drag the bar or click the up and down arrows at the right. I can highlight the address in the menu bar, copy it and paste it into Firefox or Chrome, and navigate to my heart's content. Besides WIndows Explorer, I have a few other programs this often happens with while the majority of my programs work fine all of the time. Usually I can restart my computer and then it is fixed for a while but the issue shows up again later. Most programs do not have this issue and the affected programs work perfect on my other PC's, I wonder if it is windows 8 related, hardware related, driver related, or software related. That problem has persisted through multiple OS, software, & driver updates over many months. Unfortunately this is hard issue to describe concisely enough to search forums for solutions for. The notebook is an HP Envy DV7 7259nr (i7 3630QM @2.4 GHz) running WIn 8.1 Pro 64-bit.
