In DejaContacts on the right side I have the thin scrollbar and all letters A-Z.
I thought when I click one of these letters the list will "jump" to the first entry which name starts with this letter.

I'm not really able to use one of these letters for this purpose.
Sometimes I hit one letter, which then is displayed in the middle of the display and the the list jumps to this position, which is correct.
But most times I do not strike the letter; the contact which lies under the letter is opened instead.

It seems to me that it is very hard to hit the correct position at the right side.

What can I do to get this function working better?
