Blank Frozen Drop-Down menu bar on AC29 on Mac

Two of my colleagues have exprerienced this on AC29 and their hotfixes are uptodate. This happens when you click on 'File" or Teamwork" and then when you move on to the next tabs, it freezes as shown below and it can not be removed unless you close the file. Has anyone experience this issue?

There are lots of reports of this now. There is a post on the front page of the community that was next to this one until I commented on it.

it’s a weird one that cannot yet be pinpointed.

Hello Graphisoft,

Did you found a way to correct this problem without having to restart archiCAD ?

I found the way to create the bug :

Have ArchiCAD open on one of two monitors.

First, you have to "be" in another software (web browser, mails...) on your other monitor, and the archiCAD windows has to be "grey". Then before clicking anywhere in your archiCAD windows, click directly on the dropdown menu. It will reproduce the bug.

You can even have several dropdown block like this (image)

Hopefully you'll find a way to correct it soon.

Yes, there is supposed to be a fix on the way.
