Hello, We have installed beta version 1.22 on a brand new HP windows 11 touch screen laptop. The first day we were programing I clicked the Child Window button and it worked, opened up the second window, I was able to click it again for it to go away / close and click again for it to open back up.
Now a couple days later it is no longer opening the second window. I have tried it in windowed mode, maximum sized & full screen modes with the same results. Tried rebooting the computer, tried with and with out the showxpress interface attached. Today I updated to beta version 1.25 and re tried all the mentioned steps and still am not able to open the Child Window. I also just tried going into Manage Lightshow to create a new show file / project, doing that caused the program to crash. when I reopened the program it was in my new empty "test" project file, Child Window button still was not working. Re opened my original project and it did not load any of my Boards but was able to "open" them in the boards page to be back were I left off.
When I click the button it does turn blue and the main "TLC" window label (labeled in the upper left hand corner of the program window) goes grey like it Did open another window but it is no where to be found and does not show up if you mouse over the icon on the taskbar, only the original window is shown. Sometimes I see a ghost "box" of were the Child Window would be opening but disappears just as quick as it appears.
Did not make any notable changes between the day it Was working and the couple days later when it was not working. The laptop was off and is not used for anything other than running this software.
Is there any known issue with this? Could it be some type of Windows or HP software not allowing it to open? We purchased a portable second touch screen monitor to use once we discovered this buttons potential but now am at a loss after trying everything I could think of.
Thank You for your time.

There is a page with a button "ask for authorization to download the file".
We clicked on this button and we are now waiting for the authorization.

Please try opening "regedit", go to "HKEY_CURRENT_USER" => "Software" => "EFK" => "theLightingController" and delete all keys related to "childWindow_*"gizmomeow wrote: Tue Jul 29, 2025 10:18 pm Now a couple days later it is no longer opening the second window.

Hello,
This Worked!!
Could you say what I did to end up in this position?
Only other thing I can think of is I had my personal secondary usb C touch screen monitor (was not used again on this computer) connected to this laptop on the first day and had the child window on that screen maximized when I closed the program and shut down the laptop.
Thank You Much for the assistance!

Re: Child Window no longer Opening
It seems that coordinates were saved and then the screens were rearranged so that the child window opens at coordinates that no longer exist. We will see what we can do on our side to avoid this.
