I got a problem with my 4Bit Gray grafix in the Constructor.

I do this:
I have a 8 Bit color image copy it and paste it int the bitmap object in the 
constructor, that works fine. Than decrease the colordepth to 4 bit, gray. 
copy again the whole thing and paste it in a new bitmap object, but this 
time the image is corrupt, I can only see a almost plain grey picture.... in 
the object window...
When I than decrease the picture to 1Bit copy, paste... everything is fine.
Is there maybe a problem with the 4Bit coding in PSP? 
What program do you use?
Any suggestions?

Thanx
RV

ps: I am using CW7. Don't know if this is important to you.

   PSP as in Paint Shop Pro??  I have seen this an it's a Constructor problem.
The images I've imported to Constructor, I've imported via copy/paste from
LView, and NOT had an easy time of it.

   I don't remember all the specifics:  But I remember last time I tried
importing a large (100x100) image, it gave me all kinds of crap.  (Small
images I just copy pixel-by-pixel, to avoid this nonsense)  If I remember
correctly, to get around the idiocy, I had to change the palette of the source
image before copying and pasting it over: Something like there had to be a
certain number of colors in the image's palette, whether or not all those
colors were actually used.  This is trouble since some programs auto-reduce
the palette to just the colors used.  Plus I had problems with Constructor
changing colors, black to purple for instance.  Very irritating.

   I'd recommend just bringing that particular resource over with PilRC.  :)
It's not completely deranged.
