Combobox On Editor Toolbar

Hello. I added a DHTMLXCombo with some font names to the toolbar for the DHTMLXEditor. If the user selects text in the editor, then selects a value in the combo, the editor loses focus. If a user selects text and then clicks the Bold button, or Underline button, the selection in the editor remains and the selection changes to bold or underline.
How can I select text, then select a font in the combo, and have the editor selection remain so that when I run a runCommand, the selected text font is changed?

Thanks
Scott

Any thoughts on this?
