using Version 4.0:build-30 on opensuse 12.3
write "W2" in cell A1
choose font liberation sans
choose font size 24
in cell A1 only " 2" is visible, W is invisible
I tried with many fonts and it happens only with size 24
I tried with other numbers after "W" and it happens also
would you please to test in your systems???
thanx, ciao pier
