Just to inform you – yesterday I had a database with a very large table that would not export properly and hung SQLYog with the only option being closing SQLYog from the Task Manager.
I just noticed today that now all my saved connections which were stored in sqlyog.ini are gone, even though 2 of them were still open and are being restored upon starting SQLYog.
Maybe the timing of saving of the INI-file is a little off.
