Attach one window to another window in Ubuntu

Hello fine Gentlemen,

i have the following problem and i primarily want to have a way how to analyse this. My problem is that somehow Ubuntu keeps locking me in a certain window/editor. i can then not switch to another one using the mouse or Keyboard. I can however close the window, giving the focus to another window.

I am using qt to write linux application, tested under Ubuntu. I set the main window stay on top and fullscreen, and make other children windows, but soon these window go behind of the main window as I click on the main window. Is there any way to avoid this and keep children windows stay on top of main window? Thanks beforehand

Ubuntu(or maybe just Unity) lags whenever I minimize a window when there's no other opened window(others are minimized).

I faced this problem after I install Ubuntu Tweak 0.7, Conky, OpenJDK 7, IcedTea 7 (if it does matter)

There's no problem to:

show and hide windows spread window open and close window

I have set window minimize animation as Fade 220ms and Animation Time Step as 1 in CCSM b

Generally, when i download a file, firefox will opened a small download's window for me. Let's say ... if I minimize both windows. The window, which able to be re-maximized is the download's window only. I unable to maximized the FF's main window.

Is it normal? how can it be solved?

In order to re-maximized the main window is: I select the downloading file, and open the download page.

Wise ones,

Okay, so I've managed to commit a couple of newbie fumbles.

First, whenever I minimize a program window, such as a browser, the window does not "drop to the bottom of the screen" and, in the form of a button, take up placeholder residence in the panel. Instead, the window shrinks down to nothing and simply disappears from the desktop.

I'm still pretty new to Ubuntu, so please bear with me, and explain things like you're talking to a small child.

When I hit minimize on my last open window in Ubuntu 11.10, everything freezes. I can't open a terminal window via Ctrl Alt T, I can't hit the superkey and open Unity, I can't click any of the icons on my panel.
