Problems with org-drill

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?

Yes and you can remove the line

(set-window-start nil window-start)

from defun org-toggle-latex-fragment in org.el for a fix.  I use this
fix for a while and have not seen any (unwanted) side effects yet.

The real issue may be somewhere else though.

Anything new about this problem?  I also experience the bug, it's still
present and I have to remove the given line on any Org update. :-(

I'm still trying to find the bugreport for the bug mentioned here in

I just started using org-drill, and I'm seeing the same issue (using
current org-plus-contrib from elpa). I tried to follow the link to the
"little function" but I get a 404. Any suggestion to get rid of the bug?

Thanks,

Alan

I updated to the latest org-plus-contrib and all is well now. Thanks a
lot!
