After leaving Sylpheed open for while along with a email preview window, if I try to move the email preview window it will move about a half centimeter and then freeze. When it freezes, the mouse becomes confined to the desktop region minus the taskbar region. In addition, I can no longer interact with either main sylpheed or the email preview window. This freeze will last anywhere from about 30 seconds to 90 seconds; at about 90 seconds, sylpheed crashes and it closed by Windows. I've struggled with this issue since the 3.5.0 release came out, and just today downgraded to 3.4.3 which never had this bug.

I have received several reports of similar issues,
but I cannot reproduce them yet.

Could you give me additional information?

  • OS version (Windows 7/8/8.1/10 32/64bit)
  • How long had you left open Sylpheed until the freeze occured?
  • Any details of configuration
    • separate folder tree/message view
    • interval of auto check new mail
  • sylpheedrc config file

  • OS is Windows 8.1 Pro 64bit
  • In almost every case, Sylpheed had been open for a relatively long time (maybe 24+ hours minimum). This freezing did not occur when sylpheed was freshly opened.
  • Freezing would only occur if separate message view window was open (usually for a decent period of time; 1 hour+) and if I tried to move this window by "grabbing" the titlebar to move.
  • Main Sylpheed window layout is: folder tree on left, right is split with message list on top and message view on bottom
  • Auto-check email occurs every 10 minutes; 6 accounts total
  • sylpheedrc file is attached

I'm not sure if it helps, but could you try the new GTK+ library?

1. Quit Sylpheed
2. Overwrite the Sylpheed 3.5 installation folder with the contents of the attached zip

It took me a while to get the new GTK+ library implemented, and then testing took a while longer. But, I can say that the window pane freezing on separate message view windows still occurs.

#5 Updated by Tom Peterson about 3 years ago

The problem has become prevalent enough that I'm going back to v3.4.3.
