Enhancement: Very hard to resize the main window

[esrat]

Having to live with the Windows-10-look of the "windows" on Windows 7 Professional 64-Bit, I do not want to get all the Windows-10-usability-problems as well. On Windows 7 there are no issues when handling window positions and sizes, but there are with the WFN windows!
Until some minutes ago, I even thought it was a fake resize handle, shown on the bottom right, drawn right above the scroll bar handle (see the screenshot for #134). But there seems to be an excactly 1-pixel-wide border to resize the window which I hardly ever hit on my more-than-full-HD screen which is totally common these days.
