WebDriver and IE10 very slow input

When I'm trying to execute tests in the latest IE, I see that input is very slow : it takes like 5 seconds for every character to appear in the input field. All security zones are enabled and the driver initialized with the following code:

System.setProperty("webdriver.ie.driver", "./src/test/resources/IEDriverServer.exe");
return new InternetExplorerDriver();

This problem appears only on IE10 ; when I'm running Firefox everything is just fine.

My OS is Windows 8, just in case.

Did I miss something?

UPD Now i can see that sometimes IE works faster, but when it happens this code doesn't work:

action.contextClick(logoPic).clickAndHold().sendKeys("keys_to_invoke_some_window").perform();
