I’m re-posting this issue from the Opera for Mac forum, as this seems to very much apply to Opera 10 for Windows.
Is this a known issue? I seem to be one of many who are experiencing it. Please advise.
“I've been using opera for the past year and have had Facebook Messenger and Whatsapp Messenger in my sidebar. They worked perfectly until a couple of weeks ago when all of a sudden both messengers started lagging heavily. Typing is slow, if I click on something, it takes about 5 seconds for it to finally load/register. Is anyone else experiencing this and if so, is there a fix? I loved having them connected to my browser but it's more of a hassle than a help now.”
