A customer received an EArgumentOutOfRangeException in the TAdvToolbar's SetToolBarTopAndHeight procedure at this line attempting to GetItem.
if (ATop <= Items[aAdvToolBar.Row].RowRect.Top - 3) and (ATop >= Items[aAdvToolBar.Row].RowRect.Top - 5)
and (Items[aAdvToolBar.Row].ToolBarList.Count > 1) then
It was opening and creating a new form that contained the toolbar. I cannot reproduce it, so it may only occur for a particular scenario. Perhaps you can see something that might cause it.
Display mode (from EurekaLog):
\.\DISPLAY1[PRIMARY]: 3840x2160x32 168 DPI @ 0x0, \.\DISPLAY5: 3840x2160x32 144 DPI @ 3840x0
I cannot tell by EurekaLog's screen shot, but the by design, the modal form should appear in the center of the owner's form (poOwnerFormCenter). EurekaLog's screen shot only shows the caller form and the mouse on the button that launches the form that is generating the error.
TAdvToolbar 6.8.3.8
Delphi 11.2
