Win10 version 21H2 build 19044.2130
I have noticed that sometimes a rightclick on roughly the bottom half (with some variation) of the titlebar is ignored. It's only the rightclick, leftclick is not affected. It's only when the window is not maximized. It only happens with specific skins and only with specific programs, it is consistant in that regard. I do not know if this is new with WB11.
I'll mention that I also have WinFX running, but turning it off doesn't seem to affect this.
Set the WBConfig Setting "Action to take when right clicking on a title bar:" to "Show System Menu" or "Use Style Setting", the other options there seem to work fine.
Load one of these shipped skins:
Acrylic 7, Corporate, Eva, Ice, The Caption, Win8, Win8 Metro. I don't see the behavior with the other shipped skins. I do see it on a few other skins I have installed.
Start up one or more of these programs:
Task Manager, Notepad, Notepad++, DreamMaker Pro, SkinStudio. (Some programs I specifically do not see the behavior with: Windows File Explorer, WBConfig, SpaceMonger, WinFX Configuration, Chrome, Edge.)
When the window is in a normal non-maximized state, either active or inactive, rightclick on the lower half or so of the titlebar, nothing happens. Rightclick on the upper half or so and the System Menu appears.
I have noticed that the SKS "OS Caption Height" setting affects the behavior, but it doesn't seem like that would really be a solution. For example, changing that setting on Corporate from 26 to about 40 corrects it. That seems high though and would probably cause issues elsewhere.
Thanks, hope this makes sense.
