Sandboxie Support

An applications want's to cerate a new child document window. After sandboxie is showing the error message, the application crashes.
Never had this issue with version 3.x.
Any ideas?

If you are getting this message then you must be on Windows 8.
MDI windows behave differently in Windows 8 and I included support for this but it does not cover all use cases.
If you tell me which program is triggering this error, I may be able to look into this in the future.

Yes, correct. Windows 8 / Sandboxie 4.0.13 x64
The application is a special piece of software used in the avation business. From a company called Jeppesen. But nevertheless, it looks like a standard Microsoft C++ app. Including all the runtime DLL's which are known from the Visual .Net framework...

Perhaps if you add an exclusion for * (a single wildcard star) in Sandbox Settings > Resource Access > Window Access it might be a way around this problem for now.

Have the same problems on Win8x64 with current Sandboxie Beta ( 4.0.13)
Tried exclusion * in Sandbox Settings > Resource Access > Window Access but it not helped.

If you need an example Tzuk, you can try with that program: IRT Student Edition

Thanks. I'll give it a look after I release the official version.

Windows 8 (64-bit)

Both Sandboxie 3.76 and 4.02, officially, give:
but 3.76 creates (and shows) the Child window(s) where 4.02 does not; leaving the odd (if not all) MDI application(s) unusable under Sbie 4.

After reinstalling 3.76, I didn't think to test OpenWinClass=*

A pure Win32 based MDI application

Thank you everyone who provided sample programs. Please check version 4.03.01.

Version 4.03.01. fixes the problem for all programs with which I had it before! Great and THX!!
