  • When i open dev tool. then open it with new window
    the re-do it, it toggle to side.
    but not really like what i expect, opera got a crash all the time. So now I can't open Dev-tool side mode, just new window dev-tool and I dont feel good at all.
    thank you!

  • Known issue, you will see a couple of threads about Developer Tools causing Opera to crash when you try to dock it.
