c# - WPF Incorrectly Showing the Taskbar After Clicking a Window -

I have a bug with the WPF application when a user performs an action in the program, then "Wait for" window Is started. This window remains active until some information is processed, at which point the "Please wait" window is removed

The problem is that when the "Please Wait" window becomes active , The user is able to click on the screen and the taskbar is shown. The application is not low, but the "wait bar" window appears until the work bar appears above the program on which the work bar disappears

Here the settings for the "Please wait" window Are;

  ResizeMode = "NoResize" MaxHeight = "500" MaxWidth = "400" WindowStat = "normal" ShowInTaskbar = "False" ShowActivated = "False"  

I have another window that appears with more general warnings, which does not have any issue in the workstation that appears when clicking on the screen. There are settings for that window; ResizeMode = "CanMinimize" MaxHeight = "500" MaxWidth = "400" WindowStat = "normal"

I think this is the most confusing one There will be a problem in the window, but the second window (which is almost a carbon copy of the earlier, with a different button) does not.

I am not sure that I have provided adequate context and background information about the program and the problem. I imagine more information will be required, but at least I am hoping to solve this problem - or discuss this with others if someone experiences such an issue in this way.
