Droppable AvatarImage breaks

[looter]

I'm having an issue with a droppable DPanel after I attach an AvatarImage to it. After parenting an AvatarImage to a DPanel and adding it to a DIconLayout, the AvatarImage is unable to be moved, and DoClick doesn't get called on either of them. Any ideas on how I could parent an AvatarImage to a droppable DPanel and maintain its functionality? Code to reproduce below. Place the code in autorun/whatever.lua and use the console command dropbug.

[lua]
if SERVER then

AddCSLuaFile();

else

concommand.Add( "dropbug", function( pl, cmd, args )

local main = vgui.Create( "DFrame" );
main:SetSize( 400, 400 );
main:ShowCloseButton( true );
main:Center();

main.AreaOne = main:Add( "DIconLayout" );
main.AreaOne:SetPos( 10, 30 );
main.AreaOne:SetSize( 138, 74 );
main.AreaOne:SetSpaceX( 5 );

main.AreaTwo = main:Add( "DIconLayout" );
main.AreaTwo:SetPos( 10, 168 );
main.AreaTwo:SetSize( 138, 74 );
main.AreaTwo:SetSpaceX( 5 );

-- Non Avatar slot
local Slot = vgui.Create( "DPanel" );
Slot:SetSize( 64, 64 );
Slot:Droppable( "slot" );
Slot.DoClick = function() print("Slot was clicked!\n") end

local item = main.AreaOne:Add( Slot );
item:SetSize( 64, 64 );

-- Avatar slot
local Slot = vgui.Create( "DPanel" );
Slot:SetSize( 64, 64 );
Slot:Droppable( "slot" );
Slot.Paint = function( w, h ) end

Slot.Avatar = Slot:Add( "AvatarImage" );
Slot.Avatar:SetSize( 64, 64 );
Slot.Avatar:SetPos( 0, 0 );
Slot.Avatar:SetPlayer( nil, 64 );
Slot.Avatar.DoClick = function() print("Avatar was clicked!\n") end

local item = main.AreaOne:Add( Slot );
item:SetSize( 64, 64 );

main.AreaOne:Receiver( "slot", function( pnl, tbl, dropped, menu, x, y )

if ( !dropped ) then return end

local item = pnl:Add( tbl[1] );
item:SetSize( 64, 64 );

end );

main.AreaTwo:Receiver( "slot", function( pnl, tbl, dropped, menu, x, y )

if ( !dropped ) then return end

local item = pnl:Add( tbl[1] );
item:SetSize( 64, 64 );

end );

main:MakePopup();

end );

end

[b]Edit:[/b] Fix thanks to ChewGum, combination of SetZPos and SetMouseInputEnabled solved the issue.
