Re: WinDrawChars problem

Try 
void DrawString (CharPtr str, Short x, Short y, Short width,Boolean
rigth_justified)
{
    Int strLen;
    CharPtr ellipsis; //char ellipsis;

    Boolean stringFit;
    
    RectangleType    rect;

    WinEraseRectangle ( &rect,0);
    
    // Check 1: Debe existir el str
    if (str == NULL || *str == '\0') return;
    
    ptr = StrChr (str, linefeedChr);
    if (ptr)
        charsToDraw = (Word) (ptr - str);
