Gold icon dissapearing

[Rotflturion]

Okay, I am not sure what causes this, but the gold icon in the inventory randomly dissapears when picking up other objects.

Sometimes it dissapears after 4 items, sometimes when picking up last item before inv is full.
Also sometimes it appears, but as an item with PINK rectangle [that should normally be invisible]

I am not sure if it could be that, but I have just made a little piece of code based on two different tutorials ['onClick' tut, and 'Chests' tut], that gives the player an item when he *clicks* a tile with his mouse.

The code:
```
        Dim b As Long
        b = FindOpenInvSlot(index, 4)
        If Val(ReadINI(GetPlayerName(index), "Test Chest", App.Path & "\data\Chests.Dat", 0)) = 0 Then
            If b > 0 Then
                Call PlayerMsg(index, "You open the chest", White)
                Call SetPlayerInvItemNum(index, b, 4)
                Call WriteINI(GetPlayerName(index), "Test Chest", 1, App.Path & "\data\Chests.Dat")
                Call SendInventoryUpdate(index, b)
            Else
                Call PlayerMsg(index, "You don't have enought free space.", White)
            End If

        Else
            Call PlayerMsg(index, "It is empty.", White)
        End If
```
I do realize this is the saddest piece of crap some of You saw [using INI = hate, but they're easiest for me], but it works.

I did not observe such behaviour before.
Any ideas what could cause this?
