Problem with delimiter splitters in Windows Explorer (Win 7)?

Question

Windows

Colleagues, good afternoon,
My question is this - does anyone other than me experience problems with splitters-separators in the Windows7 explorer (I mean Windows Explorer, which is called by Win + E)?
Briefly - for those who do not like to read a lot of letters - when moving the mouse around the separator in extreme positions, the cursor still shows that capture is possible, but when the mouse button is pressed, capture does not occur, the cursor changes to normal.

How to deal with this (if this happens not only to me)?
The prehistory is as follows - after switching to Win7, I began to notice that when moving vertical separators in the explorer, sometimes the separator does not “cling”, and you have to move the mouse again and drag the separator again.
I mean these separators:

I'm no longer young, but I don't seem to suffer from tremors yet. I began to watch closely what was going on.
When the mouse pointer crosses a separator, the cursor changes. This happens at the moment when the cursor center is aligned with the separator line, which is logical (perhaps it would be better to change it when it enters the capture area).
After the cursor has changed, we can move it left and right within plus or minus two pixels:

So, if the cursor is in the “extreme” position (the center is two pixels away from the separator), then when the mouse button is pressed, it simply changes pointer, and nothing happens (these are positions 1 and 5 in the picture above).
I have a trackball at work, so the mouse is guaranteed not to move when the button is pressed. On a laptop, the buttons are also separate.
How to reproduce this - hover over the separator until the cursor changes, then gently move the mouse cursor a couple of pixels to the extreme position (the cursor should not change) and try to capture the separator by gently pressing the button - I miss it. To make it easier, you can slow down the mouse cursor and turn on the magnifier. With a horizontal separator the same garbage. I don't see this in other programs. A search didn't turn up much, as the internet is littered with problems where separators don't move at all. Contacting tech support - I doubt it will help. There, it seems, the second bug also sits when moving the pointer one pixel back from position 5 to 4 or from 1 to 2, the cursor changes to a pointer, although it should not.
Although this is only “one pixel”, and the bug is on the verge of “cosmetics”, this behavior is incredibly annoying, although it trains “hardness of the hand”. I watch it on three computers under Win7. To check, I put the seven in vmware - the same thing is there. Turned on the Windows Classic theme without the bells and whistles - the same effect. The explorer.exe version is 6.1.7600.16385.
So I want to ask before I get into the debugger - this apparently happens not only to me? Maybe tweak something in the registry? I understand that Q&A is not bug tracking, but still. After all, if this is the case for everyone, then something needs to be done?

Answer 1

I won’t give an answer, but I just checked it on windows 8. There is no such bug here, everything is fine in the extreme position. Incl. now you have a meager reason to upgrade =)
