Bug with 16CF0000 style windows

[rp1231]

When the option is set to "move window" on left mouse button on title bar:

There is a bug which affects only 16CF0000 style windows
(eg. notepad++ and Anlink):

You can only click the top half of the minimize button to minimize the window,
If you click on the bottom half of the minimize window it either glitches or maximizes the window:

This is a windows bug, there is not much I can do about this outside of disabling titlebar actions all together
See this post #83 (comment) for more details

Ah ok I see.
In that case,
Would it be possible to add an option in the .ini just to enable a permanent window snapping to the screen borders for all windows in all situations.
That way it doesn't need to detect the titlebar, all windows will just snap to the screen borders.

Window snapping to the screen borders is the reason, I enabled this feature.

Sorry if this doesn't make sense.
I'm just hypothesizing.

Actually it is not really possible.
AltSnap only interacts with windows movement for a reason, one of them is Alt+Click, an other is titlebar click.
In this latter case AltSnap detects via a WM_NCHITTEST message that the click was performed in a titlebar and performs the titlebar action instead of letting windows handle the click.
The way to go would be to improve titlebar detection with an additional heuristic in addition to the WM_NCHITTEST message. this could lead to other bugs however. I am still invistigating for a better solution.

Ah ok I see.
Thanks for the explanation.
