Ok due to two reasons I installed this JWM - one I was already looking for something else to use for a desktop - just for a change - and two: someone in here put me up it it because they did it, so I tried it, and its nice. But,
I use a script to change desktop images (random images) it works, then when I used it in this jwm it works but how this is working it not good.
when one sets jwm up to show a different image on each desktop. it will call to change the image when one changes the desktop so that right image will show when it is suppose to.
The advantages of the tags options one is command, to execute a command instead of an image, therefore scripts too can be used within this option of separate images for each desktop.
my script has within it a means to check PIDS count if more than then kill the extra ones so process will not get over ran and have more than one of these scripts running at a time, therefore keeping the changing of the image on the background to just whatever it is set up to time change in the script.
in other words change time is set to 1 minute that script controls that, but if another run of same script is ran then it changes too.
now two scripts are changing the image at accordance to their start time.
hence kill the extra pids to prevent changing the image more often than 1 minute.
Within my script when executed the function to check PID count and kill PIDS if more than will be called every time the script is called to execute.
The JWM : when ever one changes to the desktop then whatever is within the tags will be called to execute upon change.
So logically when ever I change my desktop to the desktop that executes the script. then upon that script execution it is SUPPOSE to be calling that function that checks PID count.
But something is awry .. it does execute my script every time I change to that desk top, I can tell just by how I got it set up to work.
to set a given image upon execute to take up lag time waiting for a minute to pass before cycle starts to set random images.
then then next thing that is suppose be happening in that script is that function call. which is not being done for some strange reasons.
script is this:
it is not that complicated. Is is only three functions.

#!/bin/bash
WALLPAPERS=/media/data/wallpaper

Of course this works when I run it in a command line.

the only reason we do not see one instance of the script running now is only because I added the call right after I defined it. as noted above in the code.
If I remove that extra call it works in the command line, as well if I just use it to be called in an "autostart" method in this WM as well as any other Desktop or Window Manager.

I do hope I have not boggled the minds of anyone with this.
