WOW!!! It seems to help, although I do not know what I did with that - google 
does not provide clear enough (for me) description.

So, I pressed Alt-Ctrl-F12 and received the black screen with blinking cursor, 
which was expected...:-)
Then, I pressed Alt-Ctrl-F1 to return to the graphic screen, but now kdevelop 
seems to work fast back!!

What does it mean? How does it work?
Thanks a lot ahead for clarification!!!
And a lot of saved time and nerves!!!
