Hi Jon,
Thanks for the follow-up.Also thanks for the link to Winspector.
Very useful.I used to use WinSpy, but this one is much better.
To be sure, the incidents of the window popping up are less now,
but still involve the following settings -any one of them:
Enable Taskbar Buttons.
Enable Windows Snapping
Enable maximized window dragging
Enable middle click window moving
Under Troubleshooting
Enable global mouse hooks
Enable global application hooks
But my latest tests showed it to be inconsistent.(with the beta version)
e.g. Screenshots were taken with the HookManager window showing.
After the second shot it disappeared and sofar hasn't come back.
I've att'd 2 screenshots - hope that's what you were after.
To physically show that window for yourself,you could try Fabertoys
http://www.faberbox.com/fabertoys.asp
and Windows Explorer section
http://www.faberbox.com/products/fabertoys/images/windowsexplorerbig.png
When in that section you can tick the box to make the window visible.
Initially it will show the existing state, which in my case was "visible".
Unticking it , will make the window disappear,but if the program or other interference
insists on it being visible, the window will re-appear as soon as FaberToys is closed.
However,sofar so good
I'll keep you posted on further developments.
Pete.
