Overview 'My virtual machines' has a scrollbar for both column values and column titles
In the overview tab, 'My virtual machines' has a scroll bar for both the columns titles and column values.
I believe this wasn't intended and isn't often seen. Typically they move together so you can more easily associate values with titles/labels.
On the overview blade, there is a scroll bar only to scroll down to view a list of VMs. Can you please elaborate on the issue you are experiencing?
