Avast Free 6.0.1367 + W7x64 + Internet Explorer problem - SOLVED

[vladimir1433]

After update from 6.0.1203 to 6.0.1367 i can use only one Internet Explorer window. The second open window freezes.
After uninstalling Avast everything is working again. After a new installation of Avast is a problem with browser back.

Avast Free 6.0.1367 (autosandbox off)
Windows 7 x64 Home (fully updated)
Internet Explorer 8
Sandboxie 3.50 (may cause problems...)

Can anyone confirm similar problems with IE?

No problems with IE9 on my Windows 7 system.

I do not use Sandboxie though.

I have AutoSandbox set to Ask.

I suspect a Sandboxie conflict. Have you tried turning it off and then see if you can open up a second tab in IE?

[vladimir1433]

I certify that this is a problem with Sandboxie. Turning off Sandboxie not help, but the uninstallation Sandboxie yes.

Thanks for your patience.

EDIT: Sandboxie 3.64 from 7.2.2012 solves the problem.
