In STAAD, there are some of windows can be expanded by drag
But some of them does not. Especially Loading Tab.
When the name(combination) of load is long enough larger than "fixed window width"
Then, user should use the drag arrow to see/check what the name(combination) of load.
Frankly, it is a bit cumbersome.
It has been a quite while after CONNECT edition released so there's lots of time to fix it, but it is not yet.
I'm quite sure that most users have uncomfortable from it.
