I'm the author of SCRNBLNK.  It uses VioPopUp to blank the screen, and this 
does indeed seem to suspend the foreground session, at least sometimes.
I haven't yet figured out a way to avoid the problem; any suggestions 
would be welcome.  I've thought of a couple of other ways to do the 
blanking; but they all have other problems... 

Only full-screen (non-PM) sessions seem to experience this problem; PM
sessions continue without being suspended.
 
For anybody who wants the program, a slightly newer version is in the file
OS2:SCRNBL12.ZIP at mtsg.ubc.ca . The original version worked only with OS/2
version 1.1 ; the new version works with 1.1 and 1.2 .  There are some minor
problems with the 1.2 version due to bugs in OS/2 1.2.   

There is a desktop picture program that includes a screen blanker; I think
it has been distributed on this list.  It blanks ONLY the PM session, as 
far as I can tell.
