Here's an easy way to disable your extensions to see if they are interfering: Click the Options button in Chrome (it's the 3 horizontal lines up in the top right corner), and click New Incongnito Window. In that new window, go to Res and log into your account and visit the areas you're having trouble with. If you no longer have trouble, then you know it is definitely a browser extension causing it.
If you are still having trouble when using the Incognito window, post what version of Windows you are using, it might be related to that somehow. I know that Windows 8 is notorious for causing these types of issues, but it might be something that Cless can find a workaround for eventually.
