Excel 2000 shows WinDings in labels
I got a strange problem affecting some of my users. On some computers, the vertical and horizontal lables (1,2,3… and A,B,C….) to change into Windings. The page printing will be truncated as well. Page setup cannot be performed properly. a landscape print turns out in Portrait. and the dimensions are all out. Have not been able to resolve the issue completely.

Had tried to reload the office suite, but to some, it still does not work at all.

Was wondering if anyone would be able to assist on this problem.

Thanks in Advance
