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:

Thanks a lot,

Hello Anca,
Thanks for provided information and stack trace. At that moment I didn`t met such issue. Could you please tell me what is your version and do you have any installed service release and which one. Also could you please tell me, are you using Multiple threads in your application ?
Let me know if you have any questions.
Regards
Hello Georgi,
we have 11.2 with the latest service release (2124).
Thanks for your help,
Hi Anca,
I was looking in to this call stack and also can’t tell what can cause this.
Can you please give me more details about this scenario. Is the application using threads, also on which OS did you reproduce this issue?
I am looking forward to hearing form you?
Hi Dimi,
it's Windows XP and multithreading, yes.
I am just checking if you manage to fins what was the issue or if you manage to isolate it in a simple scenario.
Let me know if we can help you furthered with this.
I am glad to hear that.
no, I couldn't isolate it. It was a splash screen which we show as long as the main screen loads. I had to rewrite some code parts and now the issue is gone.
Thanks for your support,
