Focus issue when switching between ForeUI and other applications

Example that illustrates the issue:

1. Edit a Text Label:

2. Switch to another Windows application and back to ForeUI. Now focus is no longer in the “Text label editor”:

Now, I have to click inside the “Text label editor” again to place focus where is was before switching to the other application.

It might seem to be a small problem but it is in fact quite annoying, and as I remember this has not always been an issue in ForeUI.
