WindowsME: The main problem is the appearance of checkboxes in virtually all programs. Strange character or symbol is displayed instead, so I can't tell if the box is checked or not. Letters & numbers display ok. Other display problems: Down-Arrow (scrollbars) is displayed as a "6"; Normal Minimize(_), Restore (); and Close (X) symbols are displayed as 0, 2 & r, respectively. File corrupted? Font chosen in DISPLAY-APPEARANCE is MS Sans Serif (Western). Any suggestions?
