Hello all,

can anybody from Infragistics look in the source code at Infragistics.Win.EditorWithMask.AccessibleTextManager.AccessibleTextSubclasser.WndProc, if the message WM_INPUTLANGCHANGEREQUEST = 0x0050 is handled?

Problem: we have an MDI Application, 1 MDI Child Form is open, on it a few text boxes and a grid. The user changes the language by Alt + Shift or Click in the task panel. The whole application freezes. I could not reproduce this in a simple project. Stack trace:
