hard to hold vertical scroll bar in changes window

[gotoh]

It is hard to grip the vertical scroll bar in "changes" pane because the cursor would be changed into "resize window" mode. About 1/3 of the bar width is allowed.
(using ver. 1.37.2.0 on Windows 7)

Recently I randomly noticed that issue and after 2 years we finally increased the draggable area of the scrollbar.
The change is available in 1.68

Thanks!
It makes better.
But it seems that a half of the width is still used for resizing...
I wonder that the resizing cursor is appeared just out side of the window in many applications including simple WPF app,
but inside in fork.exe. Why?
