The last 5-6 times that I've done a bulk addition of about 15-20 keywords each time it runs and then will stop after a few minutes. If I do a manual refresh I can see that about 1/3 of the words have been added. I'll paste in the last 2/3 of the words again and run it and the same thing happens. Manual refresh and paste in the last 1/3 or so and then I'm good to go. I've been adding the new KWs before I run any checks for the day so I don't use up my 1000 queries on the API. The one thing I did notice is that when it stalls out it's usually added one of the KWs to just google (i've been adding to all three options) and not to the other two. Sometimes a result for google is listed, and sometimes it's just blank. I hate to post this since it's still *working* but if there's any way to not have to repost everything 2-3 times it'd be great.
Unfortunately there isn't because it's actually your web browser that's stalling (waiting for it to load). Since it has to query all the keywords for the first time, it can take awhile.
Someday, I might put some time into it where it adds the keywords first (instantly), then spins it just those off to be checked in it's own thread (like how the check all works). But it seems like a lot of work for not much gain (basically a one-time annoyance that applies only to people with a TON of keywords being added at once).
It's not a big issue. I changed how deep I check to 100 and today I didn't have to re-enter anything once.
