I am using FVWM2 and one of the defaults is this big box of pager,eyes,clock and other clickable boxes.
I asked someone there how to edit configure the window[s] and then asked how to find out what that damn box was called.
He suggested pstree to find out

Well that certainly gave me the info

init-+-atd
"snip"
|-xclock
"snip"
|-xeyes

But I still have no idea how to get to that part and change or delete it because to me at least this information is not telling me *where* to go to get at these applications [or whatever they are called]

So I am missing something - and want to learn.

I think that the reason that pstree was suggested to you was that pstree will attempt to present (in a visually managable way) the parent/child relationship of your running process. I have cut and pasted a sample below to demonsterate this. You can see that I am running gnome-teminal, and from there I have three bask shells running and a handful of programs running amongst them.

├─gnome-terminal─┬─bash───dnetc─┬─dnetc
│ │ └─tl
│ ├─bash───pstree
│ ├─bash───vim
│ └─gnome-pty-helpe

Just for clarification, in the first shell I am running a script called dnetc that simply launces two programs, one by the same name and one called tl.

Now in your case, you should try launching some of the programs from this mystery window, and while they are running, then run pstree and look to see if any of the programs that you have launched are showing up as a sub-branch off of another program, if so, then this is likely the program that you are looking to identify.
