I've noticed a problem with key handling on Ubuntu 8.04 when the 'Appearance->Visual Effects' setting is on 'Normal Effects'. The keyboard state gets cleared when the mouse is clicked, preventing the use of key modifiers like K_CTRL and stopping multi-selection from working.

The problem appears on all Upp apps, including the 2008.1 version of TheIde. I've also tested it with a svn version from about a week ago.

I have found a solution, but I am unsure whether it will cause any undesirable side effects, since I'm not sure why ClearKbdState_ is being called in TakeFocus at all.

In TakeFocus (X11Wnd.cpp, line 839) change:

	ClearKbdState_();
	if(IsEnabled() && IsVisible() && top->window != GetXServerFocusWindow())
		SetWndFocus();

to:

	if(IsEnabled() && IsVisible() && top->window != GetXServerFocusWindow()) {
		ClearKbdState_();
		SetWndFocus();
	}

It's very annoying that different settings on the same window manager can change it's X event profile!
