If I have a test list with 15 or more tests and I try to run the Test List, the pop up with the list of tests will appear but the option to start the test will be hidden and i will have no way to start. My laptop resolution is 1792x768 which is a widescreen display. It appears to not be tall enough to display this button. This could be solved by adding a scroll bar to the Manual Runner pop up page. 

Steps to Reproduce:

Open Test studio using a display with a 1792x768 resolution
Create a test list with 15 or more items
Select Run Test List
Pop up will appear with a list of all the tests 
Notice that you do not have access to the start button (image attached)
Making that pop up page wider does not help
