The size of the login dialog box is not fixed, and is a bit awkward.

[Sathyaish]

When the login dialog box first appears, its initial size is not most pleasing to look at. The choice of font in the dialog isn't appropriate for its size. The dialog could use a bit of resizing of its dimensions and that of its fonts.

Also, the size of the login dialog needs to be set to a fixed size, non-resizable window. At this time, it is a resizable window.
