Hi folks,

Recently, I started using the EMTEX 3.0 package.
In general the program runs beautifully. 
However, I encountered a problem  that I wishes to present to you. 
The problem is related to the use of fonts, and if I'm not totally
mistaken it is not only restricted to EMTEX.

	If one wishes to make overlays with slitex and one uses
	the \invisible command an error-message occurrs while previewing
	or printing the slides. This error-message is about slitex not being 
	able to find the invisible fonts. Since I didn 't generate these fonts
	I find the error message understandable. One way of solving the problem
	is by generating the fonts, but I find this an unsatisfactorary
	solution. The invisible .fmt fonts should be sufficient since they 
	contain the size information of the printer, which is all that is
	needed to print the "invisible characters". Can anyone tell me how
	the latter solution can be  implemented.
