Without the code on windows system we can`t get rightly a focus lHelp <br>
by an event of restore the window after hide (the window is blinking on <br>
an aplication panel sometimes). We should send an user input sentence to <br>
the foregroud window from a mouse or from keyboard to get focus (that is <br>
windows specific problem).<br></blockquote><div><br></div><div>Yes, in Windows terminology bringing to front means blinking an icon in Taskbar.</div><div>A Lazarus user however wants to see the help window right after pressing F1.</div><div><br></div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">I see some solutions of that:<br>
1. To rewrite that code by WinApi (that is simple).<br>
2. To exclude the package dependency on Mac system, but I don`t know how?<br></blockquote><div><br></div><div>LazMouseAndKeyInput must be fixed for MacOS Cocoa but that is a whole different issue.<br></div><div>Now that problem involves only Windows.

3. To fix the Application.BringToFront() function at windows to rightly <br>
bring a foreground window to a front of a display.<br></blockquote><div><br></div><div>That was my idea, too.</div><div>The method name BringToFront() is quite unambiguous.
