Bug while importing tab-files into the DB with field merging, in the case of absence value in DB but presence it in the file - import is broken, but more logically can be skip this row if value present in the file and absent in the DB and continue import.
We are aware of this problem and have a solution already. It will be released soon (few days at the most - we are in the process of releasing it) in 6.3.2 version (also in 14.7.14).
Thanks for letting us now.
I've found one more bug (it hasn't any connections with the subject of this topic)
the cursor in the "Single line text field" while typing moving not from left to right, but in opposite direction in Form view, and I'm not typing in Arabic (in grid view all is ok with typing)
(when I'm typing '123' in the Single line text field I see '321')
Sure that is really strange, we are already aware of it. Sorry about this quirk, we are working on a fix, which should be available soon (beginning of the next week).
