I cannot see a problem here.
This is a parameter listbox item:
<FONT color="#FF0000" size="10"><B>Preset : </B> <a href="preset" class="LIST" props="First preset|Second preset|Default preset" hint="preset value">?</A></FONT>
It returns in OnParamHint "preset" as href and "preset value" as hint.
This is the expected behavior.
