What is the solution to avoid the window becoming disabled when it loses focus?

edit

One solution to avoid the window becoming disabled when it loses focus is by using multi-threading. The main thread can continue to run while a secondary thread handles the window focus events. When the window loses focus, the secondary thread can simply alert the main thread without disrupting its operation, allowing the window to remain enabled. Alternatively, the window can be designed to handle focus events, such as by minimizing or hiding certain features or displaying a message prompting the user to regain focus on the window.
