Using either removeAllItems() on the combo or removeAllElements() on the 
combo's model, I am unable to reproduce this effect. For reference, my 
implementation uses com.apple.laf.AquaComboBoxUI.

Rather than posting a lengthy example, prepare an sscce [1] that others 
may examine more easily. Be sure to identify your chosen look & feel.

It may also help to elaborate on the problem you are trying to solve. 
For example, this ComboTest [2] avoids removing anything by preparing a 
number of models in advance.
