I will try to give you all of the relevant information w/o screen shots since I use A.D.D helper, as my screen shots will be darkened. Go to your Wobbly windows plug-in in CCSM, and remove the
unknown tag, then click the
+ button. A window will appear, allowing you to add to the window list. With the window you want to skip open click the
Grab button then click on the window. Then click the
invert tick box, then
OK. Voilà your done, however note that AFAIK this cannot select a single window from a single program, only selected types, so all windows of this type will be skipped. Don't fret however there may be a solution for you, the first drop-down box contains a list of
Window class will be very broad: normal, dialog, modaldialog etc.
Window Title is, you guessed it by title (probably where I would start if I were the op).
Window Name is likely a hex name or a name given to the window by the WM, and might work, as it might not be unique to one and only one window.
Window ID will be unique, but might change per session, I'm not to certain I would try it.
Window Role is another generic label: notification, panel, toolbox, etc.
Window Type is likely to be another generic name convention, and it's not likely to work for you.
Note: I could be wrong about the types, but I would try
xprop on the window to get all relevant information on it first, before making any changes, just to be certain that you select the right type.
xprop spews more info than you will need, look for these:
WM_NAME(STRING) = "Window Name"
WM_CLASS(STRING) = "windowclass", "Windowclass"
WM_TRANSIENT_FOR(WINDOW): window id # 0xc00003
WM_CLIENT_LEADER(WINDOW): window id # 0xc00001
Beware: some windows (most i think) will give output like this:
I'm fairly certain that what is in these field isn't what your looking for.
Hope this helps.
