I am having the following issues;

1. on web pages with dropdown menus when in tablet mode the list will not stay down long enough to make a selection.

2. intermittently the search charm will not stay open long enough to type a search term when in tablet mode or in laptop mode using touch to swipe to left.

I have done multiple refreshes complete reinstall of the OS, had the touch screen replaced and the hard drive replaced at the depot.

I would appreciate any suggestions.
