Opera, can't open links from other applications

view full story

https://bbs.archlinux.org – I'm using Opera on 64 bit Arch and I have some strange problems with it. For first ~10 minutes after launching Opera everything works fine, but then I can't open links from other applications, e.g. Pidgin. When I'm trying to open links from terminal it results in:$ opera google.com opera: Activated running instanceAnd nothing happens. No errors, Opera doesn't react in any way, nothing. I tried removing ~/.opera but that doesn't change anything.Another problem are red lines on Speed Dial page (they seem to appear randomly) - I think they designate alignment lines for sp (HowTos)
