Keyman 18 - does not allow Alt left key

Keyman
1

Keyman 18 is installed with window 11 home.
I have been using keyman without any problem until when Cham KakKhak keyboard suddenly caused keyboard changing from normal letters to Capital letters, and also causing the mouse to select entire sentences at a click. So, I deleted Keyman 17 and installed Keyman 18 with Cham KakKhak fonts(Legacy fonts not Unicode) and KakKhak keyboard. Ever since then, I cannot type all the final letter of Cham KakKhak followed by left Alt key.

I have deleted the Keyman keyboard (including fonts) several times and reinstalled it. I also have restarted windows11 several times after the keyboard installation. All these were without success.
I surfed internet to solve some conflicts with windows short cuts but it was not successful.
If somebody has any suggestion, feel free to let me know?

Welcome to the Language Software Community.

Can you tell us more about the Cham KakKhak keyboard? Is this a keyboard you created? Or one that can downloaded from the Internet? In order to try to find what the problem is, we need to identify the keyboard. Thanks for your help.

@Duk-Kun_Cha At first this sounds like a known bug that sometimes occurs that causes one of ALT SHIFT or CTRL key is regesterd as being pressed so it is stuck. One that we have had a hard time tracking down. Ususally, if you press the modifier keys several times is should clear or you can bring up the Keyman onscreen keyboard and click the modifier that is highlighted as down. Restarting Windows should have resolved the problem if this was the issue you were experencing. Since it didn’t I am not so sure.
If you find this is the issue and it is happening often you can follow these steps to turn of the seralized input queue

This is a keyboard Didi Kanjahn created. It can not be downloaded from the internet. It uses legacy fonts.

Hello, @Duk-Kun_Cha.

I sent you an email to get a follow up on @ross’s instruction and more information about the keyboard.

Thanks.
