ps script

Hi, I have a powershell script where I need to send a keystroke to a program.

I found code snippet on the internet and made little script that I tested in
windows (using powershell core) and it works.

It sends ctrp^p to notepad, and that opens the printer-dialog correctly on
windows.

On wine however it doesn`t work, cpu-usage goes up so it seems to get into
loop(???)

Script (also see attachment):
###################################################################

Start-Process "notepad.exe"
Sleep 3

$WindowHandle = Get-Process | Where-Object { $_.MainWindowTitle -Match
"Notepad" } | Select-Object -ExpandProperty MainWindowHandle

[void][System.Reflection.Assembly]::LoadWithPartialName('System.Windows.Forms')
[System.Windows.Forms.SendKeys]::SendWait("^{p}")

#####################################################################

Steps to reproduce:

1. winetricks -q dotnet48
2. wget
https://github.com/PowerShell/PowerShell/releases/download/v7.0.3/PowerShell...
3. wine PowerShell-7.0.3-win-x64.msi
4. Save the script from attachment as a.ps1 in current folder
5. wine pwsh -file ./a.ps1

Notepad opens but nothing really happens and cpu-usage goes up

Still present in wine-7.10
> From a log it goes into endless loop PeekMessage/CoregisterMessageFilter, and

just before that there`s
trace:hook:NtUserSetWindowsHookEx WH_JOURNALPLAYBACK 0x1bf3c84 0 -> 0x1007c
trace:hook:NtUserSetWindowsHookEx WH_JOURNALPLAYBACK 0x1bf3cc4 0 -> 0x2007c

With sad hack below, just stupidly returning 0 for NtUserSetWindowsHookEx it
works ok (keystroke is sent and it doesn`t get into the loop.)

So maybe the problem is in NtUserSetWindowsHookEx?

Sad hack :

     HHOOK handle = 0;

if (!proc)
