GetWindowText: Win32Exception (0x80004005): The parameter is incorrect

[punker76]

Describe the bug

Imported from ControlzEx #117

This issue started after we updated our projects to ControlzEx 4.2.2 from 3.0.2.4 and at first we thought it was similar or may be related to #103 but that was resolved in 4.2.1. I'm not making any GetWindowText calls in my code, we're using the MahApps MetroWindow which uses ControlzEx I believe, but this has been tricky for us to recreate consistently.

Actual behavior

System.ComponentModel.Win32Exception (0x80004005): The parameter is incorrect
