beta: bug with transparent colors in fields

Hi Hans,

the support of transparent colors in fields seems to be broken (beta
03.11.06). The attached example works with a non transparent
backgroundcolor, but breaks with a transparent one. Same behaviour on
ConTeXt Live.

\definecolor
  [notebackgroundcolor]
%  [s=.85]
  [s=1,a=1,t=.9]

There is another problem with field activation (not in this example).
When the doc opens, the fields (region in/out) are kind of inactive.
Normally a tooltip note is shown/hidden, if the area is entered/left.
Only after "activating" the fields by pressing "R" and "H" in Acrobat,
they become alive. After that they work as expected. I am still working
on a minimal example for this case.

Greetings, Peter
