Occasional disappearing icons from notification area!

Despite the fact that I keep the Taskbar locked, and I keep "Always show" enabled for all my program icons, invariably a few become hid until I go through the whole routine of applying "Always show" again. I really hate the ugly blue "Show hidden icons" arrow that appears in the notification area when the icons vanish. I thought perhaps it could be happening after a disk cleaning but have been able to establish that it is quite random! Any solutions would be greatly appreciated!

See line 164 at the link below and maybe line 117 both left column.

Instructions on how to use are at the top of the page and maybe unlock the taskbar when using.
