I am using Python 2.7 and Selenium 2.39.0. to test a web application. When I run my test as a Windows (7 Ent.) scheduled task with the option "Run whether user is logged on or not", it looks like the screen resolution or window sizing changes; Some buttons become hidden behind the toolbar at the bottom of the browser window and therefore, it can't be clicked by Selenium.
I don't have this problem if I choose the option "Run only when user is logged on"; even if the screen is locked, the buttons are visible and clickable.
According to the Windows task properties, it is using the same user account.
Is there a way, browser setting or a registry key which can help to keep the same resolution and size in both modes?
I know I can scroll down the page, but I am trying to understand and may be prevent this difference of behavior between these two modes.
Thanks
