8bit graphics and a not-working program

[Juntunen Teemu <Teemu dot Juntunen at tyks dot fi>]

Hi all,

I have installed cygwin and xfree in my NT to use one other program. However
this program doesn't work properly. When I start xfree with 16bit graphics
and try to display images with the program, it gives a following error: 

Displaying
X Error of failed request (invalid parameter attributes)
Major opcode of failed request: 78 (X_CreateColormap)
Serial number of failed request: 14
Current serial number in output stream: 277

When I start xfree with 8bit graphics, the program gives no errors, but
nevertheless no picture too. It shows a reddish brown window and when I move
the cursor on it, it makes all the open windows as black holes. When I hit
the right button on it (as you should get different color setting in the
program then), the program seems to react as it chages the upper task bars
colors of open windows to white and screens to black.

So the program need XCreateColormap, XStoreColor and 8bit graphics, but
doesn't work properly. Does anyone have any idea what is the problem?

I know very little about cygwin and xfree so please make the answers and
questions simple enough ;)

Regards and thanks
