Our staff in Ukraine installed Jitsi and they hit a stumbling block right away.
When they used Windows XP and 7 keyboard switcher, Jitsi froze and had to be killed via task manager.
I tested that here on Linux but did not have any issues.
Then I re-tested under Windows 7 and did could not reproduce it either.
Finally I found the difference: they were using older laptops with 32 bit OS, while all machines in our office were 64bit.
Those folks are now OK as we removed Jitsi from their machines and installed Gajim, so they can send the IMs, but the idea was to test a pilot project for voice calls using our London VOIP provider, whereas Gajim does not have voice under Windows.
Would anyone have a chance to look into the freezing due to layout switch?
I tried to collect the logs, but the latest entry was earlier than an attempt to switch the layouts, which indicates to me Jitsi was not able to flush the logs once it froze and was killed. So they logs will be of no use. We used 2.5.5065 for these pilots.
