File operations lag in Opera Developer 34.0
I'm using Opera Developer 34.0 x64 on my Ubuntu 14.04. Every time when I try to dowload or upload something, nothing happens. When I try to download a file an icon (1), (2), (3) appears in the top right corner of the Opera icon an then in about 2 or 3 minutes donload starts. When I click at file input nothing happens and then in 2-3 minute appears a window where I can actually choose a file. Opera 30 and Firefox work fine. Please help me with this.
