James D. Callahan III:
	- Added workaround for DockingStation being overly-aggressive with regard to tooltip hiding, which requires entering a different datafeed before the tooltip will show again.
	In Spamalyzer:UpdateTooltip(): Check for tooltip visibility - if not visible, cancel the timer and perform appropriate cleanup.
	- When there is no data, "0" will be displayed instead of "0.000 KiB"
	In ByteStr(): Fixed return value for values of zero or below.
	Added a comment to the empty OnEnter() for the DO.
