tray and taskbar loaded before xLabel?
also xtaskbarloadinbox set?
always on top doesn't make any sense in tray. cause when you hook anything, it will be always on top of the label!!!

and ... erm...
vtrayLabelX -157
vtraylabely -84
VTrayLabelAddToGroup "100"
VTrayLabelX "15"
VTrayLabelY "0"

2 times x and y???? doesn't make sense too
and another thing is:
VTrayLabelWidth "95"
VTrayLabelHeight "25"
you positionates the tray:
systrayX -64
systrayY -54
so this one is OUT OF THE IMAGE!!!!
like in lsBox, if you hook you HAVE TO USE the in-box coordinates and not the desktop cords.
a hooked tray on a label left top corner is
vtrayx 0
vtrayy 0
.. doesn't matter where the label cords are!!!!!!
I'm sure this is also the problem with your taskbar ;)
