I believe the bugs you are experiencing with ManageDocks may be due to
the type of getWindowProperty32 from the X11 library. The documentation
for XGetWindowProperty says:

  If the returned format is 8, the returned data is represented as a
  char array.  If the returned format is 16, the returned data is
  represented as a short array and should be cast to that type to obtain
  the elements.  If the returned format is 32, the returned data is
  represented as a long array and should be cast to that type to obtain
  the elements.

That is, the data is returned as an array of long even when long is not
32 bits wide. My reading of the above is that the return type of
getWindowProperty32 should be changed to 'IO (Maybe [CLong])' and
analogous for getWindowProperty8 and getWindowProperty16 w.r.t. CChar
and CShort. The situation is the same for XChangeProperty, I think.

I haven't tested this at all (neither on 32 nor 64-bit machines), but if
you want, you can check if the attached patches solve the problem.
