			  X Window System Bug Report
			    xbugs@expo.lcs.mit.edu


VERSION:
    R4

CLIENT MACHINE and OPERATING SYSTEM:
    All

DISPLAY TYPE:
   All

WINDOW MANAGER:
   All

AREA:
   Xrm, Xt[App]Initialize (depending on how you look at it)

SYNOPSIS:
   Executable for an X Window application cannot contain the symbol "."
   in its name if it is using the Resource Manager.

DESCRIPTION:
   Okay, so some will not consider this a bug, but to the best of my 
   knowledge it is not documented anywhere and I spent a frustrating
   time tracking this down. The character "." is significant to the resource
   manager, and so cannot be used as the name of an application. As the 
   name of an application is taken from argv[0], this means that the 
   executable cannot contain the character "." in its name. If you are used
   to setting resources by application class, then this can cause perplexing
   problems because they work fine (you explicitly state the application
   class), however command-line options using the "options" feature of 
   XtInitialize/XtAppInitialize will not work. 

REPEAT BY:
   Rename any executable to have a "." in its name.

SAMPLE FIX:
  Never under any circumstances use a "." in the name of the executable
  of an X Window application. My preferred fix, however, is to allow
  explicit setting of application names, and not use argv[0].
