When I compare local directory (big one) and FTP site (for made backup from FTP to HDD) dialog shows up with results and I can synchronize files immediately. But when I close this dialog and want to use "Synchronize" button (for uncheck some files), "Synchronize" button in main window revert to inactive. What is strange - when I second time press "Compare" and then close results window again, "Synchronize" button in main window remains active.
I did a quick check, synchronizing from a local drive to an FTP site, and the Synchronize button remained active after closing the results dialog.
If you want us to investigate it in more detail then you will need to link your account to prove that you have purchased Opus (which you've been refusing to do for months now).
Ah, you're right, I forgot. Please, forgive me and delete my post.
As I said before - I don't want to give you any personal informations, especially when you're treat people like potential thiefs.
Bye.
BTW. Some years ago I was trying to report few bugs using official bug report website - and back then I was using my purchase code. And only then.
