In my Zimbra admin area, when I'm adding a new account or using any of the admin areas to add permissions etc.
I'm finding it hard to type in the the text boxes.

For example, adding a new user of james.smith@somedomain.com when I'm filling out the LHS text box I might type james and only jme will show up. Then I'll hit backspace and it might take 5 hits of the key before it goes back 1 or 2 spaces.

The only way to do this is to punch a single key at a time and wait to see if it comes in.

Is there a workaround for this problem?
