"Unable to acquire window or process for window function" verbosity

[Pfeil]

Currently, when a window or process required for certain actions cannot be found, a "Unable to acquire window or process for window function" message is written to the log. I feel it would be useful to have the given search string included in this message.

E.G.

Code: [Select]

Display window 'ceci n'est pas une fenêtre' as [Normal]
would write something like "Unable to acquire window or process 'ceci n'est pas une fenêtre' for window function" to the log.
