v9.8 Task Panel icon size

I've added a number of group bitmaps to a task panel but the SetIconSize call doesn't seem to have any affect.  Does it work for anyone else?

The code looks something like:

 CImageList il;
 AfxSetResourceHandle( notifier->inst() );
 il.Create(IDB_VISIBILITY_BITMAPS, 16, 1, RGB(0, 0xFF, 0));
 for (int i = 0; i < 10; i++)
 {
  HICON hIcon = il.ExtractIcon(i);
  if (hIcon)
  {
   spTaskPanel->Icons->AddIcon( (long)hIcon, i, XtremeTaskPanel::xtpImageNormal );
  }
 }

 int iconSize = gPref->GetPreference("TaskPanelIconSize", 8, "TaskPanel" );
 spTaskPanel->SetIconSize( iconSize, iconSize );

Unfortunately we're using WTL but there isn't a task panel sample, so I dug up a copy of c# and modified the task panel sample (see the end of this message) but the group icon size doesn't change.  In my original message I was using SetIconSize on the task panel object (which I thought was how it would be done) but it seems there is also a SetIconSize on the group object, neither of these seem to change the size of the group icons.  The item icons change but not the group. Any ideas?

                   TaskPanelGroup Group = wndTaskPanel.Groups.Add(0, "System Tasks");

                   Group.Tooltip = "These tasks apply to your computer";

                   Group.Special = true;

                   Group.Items.Add(ID_TASKITEM_HIDECONTENTS, "Hide the contents of this drive", XTPTaskPanelItemType.xtpTaskItemTypeLink, 1);

                   TaskPanelGroupItem Item = Group.Items.Add(ID_TASKITEM_MYCOMPUTER, "My Computer", XTPTaskPanelItemType.xtpTaskItemTypeLink, 7);

                   Group = wndTaskPanel.Groups.Add(0, "Details");

                   wndTaskPanel.SetIconSize(8,8);

                   Item = Group.Items.Add(0, "Local Disk (C:)", XTPTaskPanelItemType.xtpTaskItemTypeText, -1);

                   Item.SetMargins(0, 0, 0, 0);

                   Group.Items.Add(0, "Local Disk", XTPTaskPanelItemType.xtpTaskItemTypeText, -1);

                   Group.Items.Add(0, "File System: FAT32", XTPTaskPanelItemType.xtpTaskItemTypeText, -1);

                   Group.Items.Add(0, "Free Space: 23,3 GB", XTPTaskPanelItemType.xtpTaskItemTypeText, -1);

                   Group.Items.Add(0, "FTotal Size: 76,2 GB", XTPTaskPanelItemType.xtpTaskItemTypeText, -1);

                   Group.IconIndex=1;

Group.SetIconSize( 8, 8 );

                   wndTaskPanel.Icons = (XtremeTaskPanel.ImageManagerIcons)TaskPanelIcons.Icons;

                   wndTaskPanel.Reposition();

                   wndTaskPanel.AllowDrag = XtremeTaskPanel.XTPTaskPanelItemAllowDrag.xtpTaskItemAllowDrag;

             }

use new method from 9.80:

SetGroupIconSize(long Cx, long Cy);
