Ok. Here lives the problem. I use Win2K. I don’t know if this is the same in winxp. What happens?
The Behavior Blocker window blinks twice or three times and loose focus. Alt + Tab is the problem - it’s impossible to bring the focus back to this window. Despite it appears in the taskbar, with Alt + Tab you can’t activate the window again. The only way to bring focus to this window is clickin on it with the mouse. With the window focused, of course, the keyboard links work well.
