Cranky dock and flashy Youtube probs

[cheeryble]

Hi

 

Macbook Air

10.11

i7

4gb 

 

 

1. For a long time now my dock has been acting cranky.

By that I mean if I just head down to the dock where I know I am close to an app I want, usually the dock should rise up happily to meet the cursor.

As it is I often have to waggle the cursor around the area at the bottom or worse still often have to go to the bottom corner to activate the dock.

Enough's enough......this is a nuisance and needs fixing.

(I thought of ditching the dock and reloading but I believe it's now part of the system?

 

2. While I'm here .....

If I open Youtube.......not as part of a search for a particular item but just open youtube.......it starts flashing on and off, the whole page.

I cannot enter anything in a search and have to do a "fake search" get the page up then change the search terms.

 

Any help with these two items greatly appreciated.

Addendum to No 2:

 

I think it's unrelated but when I open a youtube video it very often.....but I think not always.....will check.....starts to play then a couple of seconds later it stops and the circle starts circling as if loading. But I'm pretty damned sure it's not loading...... as soon as I click on the circle and click again it starts and plays as normal.

 

WE might as well add a 3.

 

3. my touchpad, which i use nearly all the time, seems to have become desensitised and I tend to have to give it more of a tap or sometimes even a click to get some action.

 

I've got another one but we'll make do for now :)
