Responsive design formatting problems

I am testing my website on several devices, browsers, and screen sizes and have noticed a couple of problems.

1. On a windows 8.1 pc in Mozilla Firefox – The search field prompt text “Type Keywords and Press Enter” shows below the cursor on the second line and you can only see the tops of the letters.
2. On a windows 8.1 pc in IE 11 – The search prompt text does not appear until you click the “X” to close the search bar. It then appears momentarily and returns the users to the menu bar.
3. On a windows 8.1 pc in IE 11 – When the menu button appears upon downsizing the window and is clicked the menu appears on the right side of the screen but the scroll bar for the menu is underneath the IE scroll bar for the page, making it difficult for the user to navigate.
4. On a windows 8.1 pc in IE 11 – When the menu button appears upon downsizing the window and is clicked the menu appears on the right side of the screen and the scroll bar does not take the user to the end of the menu leaving some of the menu items unreachable.
5. On a windows 8 phone, Nokia Lumia 928, screen resolution 768X1280 – The retina logo is used which makes the layout completely wrong. When the retina logo is changed in the Highend options settings to be the smaller half sized logo the display works properly in the vertical view. This may make the logo too small for larger higher resolution screens.
6. On a windows 8 phone, Nokia Lumia 928, screen resolution 768X1280 – The menu appears only momentarily and then disappears leaving the user with a blank section of the screen where the menu should be.
7. On a windows 8 phone, Nokia Lumia 928, screen resolution 768X1280 – When the screen is turned to horizontal view it switches to the full menu but the full menu extends beyond the screen and scrolling to the right leaves the screen blank on that side.
8. On a windows 8 phone, Nokia Lumia 928, screen resolution 768X1280 – When the screen is turned to horizontal view and then turned back to vertical the menu bar appears and then disappears to switch to the menu button but the tagline text on the right side of the menu bar remains under the logo with some of the letters hanging out on the left.

I have attached screenshots of these errors in subsequent posts because the “add another file” link does not work in Firefox. Are these a known issues or are there “work-arounds” that can be suggested?
