I have configured my facebook account in Gwibber since I installed Ubuntu 12.10.
Until a few days I started to notice that the program does not refresh and display notifications, when opened gwibber interface goes blank and not updated. I read in forums that could be the proxy settings or interfering with its operation but everything is correct.
Get to the end to try on another computer than with ubuntu 12.10 and gwibber but to my surprise it is the same.
Not that I make gwibber work I thought it was ubuntu but on another pc than just occurred, not to do, that I can recommend another program or how I can fix this.
