I have a problem to run Opera sandboxed if the sandbox container folder is not in the C partition (in my case E). When Opera is executed sandboxed the following error message is continuously displayed: "Salvataggio del file dei pannelli non riuscito C:\Documents and Settings\user\Application Data\Opera\Opera\profile\opera6.adr" meaning that the saving of the panel file is failed.
If the container folder is set on the C partition the problem does not occur

Thanks

Try a workaround:

Sandbox Settings -> Resource Access -> File Access -> Direct Access
Click Add
Locate that opera6.adr file, select it.
Click OK all the way back.

But note please, doing this effectively excludes the file opera6.adr from being sandboxed -- but only that one file.

^ now hold on, to be even safer though, set the Opera.exe file to be the only file that can access the opera6.adr file.

Well it worked the other way around. I did not note that but the file opera6.adr was already in the direct access list (is it set by default by Sandboxie? I don't remember I did it) I removed it and the problem has gone. Thanks

Have the same problem. I made the tzuk's tip with no result. The problem of saving the file 'opera6.adr' is still alive. Any ideas?
