The lasts build fixed the problem with the Synchronization Checklist window resizing. I tested it on both an MS Surface Book and a Dell T3400 running Windows 10 Enterprise 1703. Good to go! Thanks.

Bug reports without an attached log file are usually useless.
The new build worked properly. I also noted that a click-drag to resize the Synchronization Checklist window leaves the mouse stuck to the window and is not released when you release the click. You have to resize and then click again to release the mouse pointer. It occurs in 5.11.2 on both my Surface Book (Windows 10 Pro 1703) and a Windows 10 Enterprise 1703 desktop. Not sure when it started appearing. Thanks!
I right click on the column right boundary and drag to the right.
winscp.exe /ini=nul), do you get the same initial state?
Can you please post some screenshots?
How do you exactly "drag" on the Surface? What exactly do you mean by "column is dragged open"?
