Moving objects on canvas

Hi,

I found that when moving e.g. the statistics box with the mouse on a
canvas with root 2.23/04 (Linux, SuSE 6.0), the 'background' part of the
Canvas is not cleared. That is, that part of the statistics box which lies
outside e.g. a histogram, is not deleted and remains visible.
This applies also to the histogram itself if you move it. It does not
affect the postscript output. Is this some side effect of a modification
or did I miss a compile switch?

I tested this with the following commands:

  *******************************************
  *                                         *
  *        W E L C O M E  to  R O O T       *
  *                                         *
  *   Version   2.23/04   13 October 1999   *
  *                                         *

  *******************************************

CINT/ROOT C/C++ Interpreter version 5.14.18, Oct 3 1999
Type ? for help. Commands must be C++ statements.
Enclose multiple statements between { }.
root [0] TH1D * a = new TH1D("a","a",10,0,10)
root [1] a.Fill(3.2);                        
root [2] a.Draw()

and then moved the stats box around a little.

Bye,
Mike
