Ubuntu :: Karmic Koala 9.10 Unresponsive UI?

On Dell Inspiron 9200, with or without accelerator for NVIDEA graphics. P.S. I would like to give 9.10 a chance. have gedit and browser open (browser with the forum message being edited), then do the following:

1.This example demonstrates one problem (unresponsive single click) Use the System-->Preferences-->Mouse

Click repeatedly on the light bulb at 1 second interval ---> result: often the light does not turn on. Result: it appears that the click event does not complete. I have noticed that a mouse-out will cause the click to complete (specifically as in 2. and 3 after a brief moment (hopefully before the drag and drop icon appears).

2. Click on any icon, submit button, close, etc. takes many tries.

3. Click on any icon, panel button, link, etc. if you linger a moment a floating icon (a drag and drop hand).

4. Scrollbar button and action follow the mouse outside of the scrollbar. The scrollbar sticks - difficult to make scrollbar stop following the mouse.

5. Example, have two visible windows (for example gedit and the browser) From gedit move to browser by click on browser. ---> result takes forever to recognise the focus and click and go to the broser.

6. Unresponsive UI. In browser highlight text in textarea (with difficulty) then chose Copy (slow UI), from this window click on desktop's Applications (takes many clicks to open), from Accessories click on gedit (slow or takes more than one try), paste (speed of paste OK).
