problem: set x1 & x2 to float colormode

Dear Grass User,

Recently I meet a problem to assign my X1 and x2 graphics display
monitor to float colormode. Please help if you had met with this
problem before. The problem is described as follow.

1. I start the x0 graphics display monitor and set its colormode
   to the float colormode. There is no problem for me to do this.

2. I start the x1 graphics display monitor and set its colormode
   to the float mode by using "d.colormode mode=float". But the
   system shows me the following message and I have problem to
   disply my image in x1 graphics display monitor.

===================================
GRASS 4.1 > d.colormode mode=float
reset_color: can't set color 4
reset_color: can't set color 5
reset_color: can't set color 6
reset_color: can't set color 7
reset_color: can't set color 8
reset_color: can't set color 9
reset_color: can't set color 10
reset_color: can't set color 11
reset_color: can't set color 12
reset_color: can't set color 13

3. The same problem happens to the x2 graphics display monitor.

4. I am using the Grass4.1 on Indy machine and there was no this
   problem before but it happened from last week.

Appreciate for any advice and thanks in advance.
