FTP Log window locked?

I haven't had any more UI freezes since that new version, but sometimes there's a bug where the log window is somehow locked. I cannot close, move or resize it and I could not find any setting in the favorites for this.

How can I close this log window?

Thank you for your answer. I restarted SmartFTP again and now the Log window is gone.

I'm not sure what exactly triggers this bug, but it seems to occur only some day after I installed an update (I updated to the latest version on Thursday or Friday, not sure right now).

If it happens again I will let you know.
