[O] Problems with org-drill

[Sven Bretfeld]

Hi

I don't know how many of you guys use org-drill as vocabulary learning
software. I have started some weeks ago to learn Norwegian. The concept
and flexibility of the extension (contrib) are great. But there is a
problem (bug?).

During drill-sessions empty cards continue to show up. About 30-40% of
the questions show an empty screen. These empty screens are fully
counted as cards in the mini-buffer counter. I use to skip those "cards"
with "s" but I have the feeling that this skips real questions which
just are not displayed properly. This would mean I'm creating
knowledge-gaps in each session.

Editing these cards with "e" doesn't seems to work. It only stops the
drill-session with the point in the line where I started. There seems to
be no rule involved in those "empty screens" showing up. (But I have the
feeling they often occur after I give a card score (0-5) differing from
the score of the last question.) Neither can I see that there are
malformed entries which could explain the phenomenon.

Does anyone else have this problem and know how to fix it?

Sven
