title: Enable mousewheel on TIsDBLookupComboBox drop down list in Delphi 7
body: <p>I am using Delphi 7. I have a TIsDBLookupComboBox, a database combobox from IS Data Controls component tab. </p>
  
  <p>It works fine, it populates its list from a database... but the trouble is mouse wheel. Mouse wheel scrolling isnt working on the drop down list... How can I enable it? 
  I know it is an old version of Delphi... but I must stick to it. </p>
  
  <p>Thank you very much.. </p>
