Grid label is moving to the left when selecting the text box using Selenium Webdriver

Grid label is moving to the left when selecting the text box using Selenium Web-driver, using automation script,
This issue exists only when running the script with IE but fire-fox and chrome work very well with this :(( , we checked this issue thinking that this relates to some resolution problem, but after giving percentage resolution also the problem persistsAttachment 40162

There shouldn't be any reason why this should happen unless there is some CSS that you are applying on focus.

There is no such CSS on focus, but tstill this is happening, if there :((, if there was a CSS that's applied on focus, why it would work perfectly while testing manually :D
