Sandboxie could cause a sandboxed app fail to reset its registry settings

[sbf]

Win 7 32-bit.
Sandboxie v5.22 32-bit.
EmEditor (Latest version).
Tested on a "naked" OS.

For example, EmEditor has a command: Reset All Settings, which removes all its registry data (along with the files for settings) and restarts the app.

However, in a Sandboxie sandbox, EmEditor can never reset its registry settings. When restarted, it uses the old window size and position, for example.

I guess the procedure is:
The sandboxed EmEditor did remove its sandboxed registry data. But as it restarts, Sandboxie fetches the old registry data from outside.

FYI,
Comodo sandbox does not have such a problem. It seems Comodo sandbox adds a mark for the removed registry data:
Type: 0x39c0
Data: (zero-length binary value)

Hello sbf ,

Please provide the required information:
viewtopic.php?f=11&t=19746

According to the devs, if you delete a key in Sbie, it will be deleted --> not read from host.
If you clear the sandbox, it will be read from host instead. Are you clearing the contents of your Sandbox?

Sandboxie does the same thing.

Are you clearing the contents of your Sandbox?

No.
EmEditor resets and restarts at once.
Hope you give it a test on EmEditor.

Hello sbf ,

In order to test this behavior I need to know what are you doing, exactly.
Please provide repro steps, include any workspaces you may be using, changes you are looking at, and how are you resetting the application.

OK. Thank you.

Install EmEditor (Installer version, which will use the registry).
Run EmEditor outside (with default settings). Change its window size/position.
(Restart EmEditor. It should use the changed size/position.)

Run EmEditor in a sandbox.
Use the menu: Tools > All Commands.
Then in the (All Commands) popup menu: Tools > Reset All Settings.
Follow the prompts.

After restarted, EmEditor should use the default window size/position (if you don't have my issue).

Hello sbf,

I see the behavior. The window size is still remembered, even after using "Reset all settings".
I have made the devs aware.

As a workaround you can add the following entry under the desired Sandbox:
Open Sandboxie Control
Configure --- > Edit configuration
Find the Sandbox you wish to modify and add this at the end:
WriteKeyPath=HKEY_CURRENT_USER\Software\EmSoft

Save the changes.
Configure--> Reload configuration
Re-try launching your program Sandboxed and resetting all settings.

Here's more info regarding the WriteKeyPath setting:

Thanks for the info. I see.

I'm curious about the reason of the issue. Could you please explain it a little?
