I have been having a problem with the XQueryFont function in VMS DECwindows.

#define FontName "6x10"

/******* Load the font for text writing ******/
static void doLoadFont( )
{
    Font font;

    if(!(font = XLoadQueryFont(dpy, FontName)))
      font = XQueryFont(dpy,XGContextFromGC(DefaultGC(dpy,DefaultScreen(dpy)))); 
    else
      XSetFont(dpy, gc, font);
}

This bit of code works fine when it is executed using the local transport,
but when I set host to another VMS machine and execute the code using the
DECnet transport the program *often* (ie. not always, some machines dont 
seem to do this at all) crashes with this (or very simmilar) error message.

X error event received from server:  BadFont - parameter not a Font
  Failed request major op code 47 (X_QueryFont)
  Failed request minor op code 0 (if applicable)
  ResourceID 0x400029 in failed request (if applicable)
  Serial number of failed request 245
  Current serial number in output stream 266


According to every X book I have it is valid to use a GContext ID instead of
an actual font ID.

My question is, Does anyone have any idea what is going on here?, and, if so,
What can I do about it?
