Synptics / hal and double tap broken

Question

I can't double tap with one finger anymore here on my Samsung notebook. I have to tap tree times to get a double click effect.

Ummm..I can't work out the 'Quotes' and how to do them on this forum board..so I'll just use bold and different fonts.
But you mis understand my question...
Here is part of my original post
I could double tap the home icon when a dialogue box was open
Implying that the dialogue box is already open BEFORE I use the double tap function.
As I go on to further explain, this dialogue box could be from either WiFi asking for a password, or Mail asking for a password, or Mail telling me it can't connect to the Server.
When you have 8 e-mail accounts and you have to hit OK or Cancel  twice per e-mail account..before you can close the app...it is more than frustrating.  ..all these multiple dialogue or warning boxes and you can't get out of them without acknowledging each of them.  You used to be able to Double tap, and Swipe the preview up to close the app..or jump to another app.
I understand this perfectly, what you said:
Double clicking the home button shows the recently opened app icons along the bottom of the screen with a preview above each icon. To open one of the apps, touch the icon and the app opens.  Copy what you want, double click, open the the other app, then paste.  The preview screens are used to close the apps by slideng the screens up.  See this:
..and that is what I am trying to do.  But when one of these Mail or Wif bode Dialogues or warnings are open the double tap is not possible..it does not work.  so you can't go to the other app to copy and paste. or slide the preview screen up to close it.
