Synopsis: auto-complete window appears only for a second

Description
When a '.' is entered, the auto-complete window pops up for a very short time (about a second) and disappears.
When I start using key_down the moment the window appears, the entries in the auto-complete list are highlighted. As long as I keep hitting key_down the auto-complete window stays visible. 
But half a second after the last key_down event it closes.

It is possible to select an item from the list to produce code if the keys are
hit fast enough.


ctrl+space does not work at all (although it is not globally registered by another application)

ctrl+space does work (It was, against my conviction) registered by another application.

I somehow managed to keep the window open with no items in it.
However, out of curiosity I set the "Does completion list show an item's description as a tooltip?" to off.
Now the auto-complete window stays open as expected. 
It seems that there is a problem with the tooltips.
