I do have one final question.

If I set PS1 like this:

 PS1="\[\033]61;\w\007\]\u@\h:\w\\$ "

Everything works great, no issues at all, what is expected is what is displayed.

Now, when i make only a slight modification as such:

PS1="\[\033]61;\u@\H\007\]\u@\h:\w\\$ "

all the sudden i have a duplicate space after my prompt as in:

v468929 AT TRD-CAX40JXD:~$  ls db2Mgr.

that goes away when i hit the tab complete button to show me my options:

v468929 AT TRD-CAX40JXD:~$  ls db2Mgr.
db2Mgr.C  db2Mgr.h
v468929 AT TRD-CAX40JXD:~$ ls db2Mgr.


I'm trying to get this prompt to work:

PS1="\[\033]61;\u@\H\007\]\u@\H \W>"

but the issue there is that the > is duplicated (just like the space
above, but much more noticable).  Any ideas as to why making the title
modification to use \u@\H instead of \w is causing these issues?
