Update on this - don't know if you fixed in later versions, but the reason this was happening was because matching the whole of the initial key would make the entire match string bold. This would be too long for the suggestion field.

e.g. If you were searching for a customer "ABC001", as soon as you type ABC001, the whole suggestion would be bolded.
The reason for this is in these lines....

Code:
            If (iPos) Begin
                Send AppendText of ghoSuggestionList (Left(sValue,iPos-1)) 
                Set pbBold of ghoSuggestionList to True
                Send AppendText of ghoSuggestionList (Mid(sValue,Length(sSearch),iPos)) 
                Set pbBold of ghoSuggestionList to False
            End
            Send AppendText of ghoSuggestionList (Mid(sValue,255,iPos+Length(sSearch)))
If you do an AppendText with a blank string returned by "(Mid(sValue,255,iPos+Length(sSearch)))", pbBold is toggled back to True.
