[Denis01]

Hello,

• HTML client
• Centos7.3
• xpra proxy version 2.1-r15785 64-bit
• OpenOffice? 5.2

Error occurs (session is stopped. Browser gets back to authorisation login screen) then open the dropbox menus( Upper file menu or right button click) and moving mouse pointer inside the menu.
But it is possible to reconnect to the session again. No lost of information

In the attached file (img1.jpg) how it looks like.
And some corrections of the text for problem's description (as it is not clear enouth)

Error occurs when a dropbox menu is open (file menu on the top of the screen or right button mouse click menu inside Office document) and mouse pointer is moving across the items in the list.
Firstly the sreen is frosen (mouse pointer doesn't move) and then some wainting time (as in the attached file) and then system moves to login page. But it is possible to recconect to the session again. No lost of information
Error from log file

dropbox is a company providing cloud services, you mean "drop-down" menu.
FYI: AFAICT, centos 7.3 provides libreoffice 5.0, not 5.2, and openoffice is not provided by default, their latest version is 4.1.3

This is fixed in r15851. Please close if that works for you.

Thanks!
but even can't test for now.
As the problem with ports appeared again.
Can't start xpra with direct command from terminal.....
Rebooted server several times.. but nothing helped.
The strange thing that session is created, port is closed and in /run/user/guid/xpra/ only 2 folders (Pulse and Xpra) created and not 4 as usual.
I would very appreciate if you could log to my server to see youself ....

Hello,
Excellent!
It is fixed!

(changing ticket title since this has nothing to do whatsoever with openoffice)
