xdigit runtime error -- Help needed

[PoKung Lin]

Hi, After compilation of xgrass on USL system, xdigit does not work and each
time when I key in  xdigit under grass prompt, I will get following error
msgs:
	X Error of failed request: BadValue(integer parameter out of range 
					    for operation)
	Major opcode of failed request: 53 (X_CreatePixmap)
	Value in failed request: 0x0
	Serial number of failed request: 413
	Current serial number in output stream: 415

Can any experienced X-Window friends might pass me some hint? Where the bugs
will be?

		Thank you for any help
