#1 0.84 won't dock

[Joshua Swink]

Version 0.84 won't dock properly for me:
Linux 2.2.19
XFree86 4.1.0
Window Maker 0.65.1

How to reproduce:
* run wmtop
* drag to dock
* restart window maker
Result: wmtop appears as if it were an icon. Its
position in the dock is strangely grayed.

wmtop 0.83 does not suffer from this problem.
