Have you tried it with Maxthon 2511?
Its not working for me.

I tried with Maxthon now, and I see a problem, I'll try to fix this.

Please try version 3.43.19. Be sure to add Maxthon 2 exclusions in:

Sandbox Settings > Applications > Web Browesr > Other > Allow direct access to Maxthon 2 favorites

Ok I tried the new version and yes it works better.
Roboform bar is working but still a bit buggy. Its more misses than hits on picking up sites for filling in. They work out of sandboxie but Id say about 40% success in SB..

Thanks for the hard work you do for us

Ok.. Faves arent updating from non SB Max to SB Max.
Faves are not moving from SB Max to non SB Max.

Perhaps your Maxthon favorites file is not in the standard location?
Look in Sandbox Settings > Applications > Folders at the folder for Maxthon.

The bookmarks are in the default location Tzuk..........
They are stored in the 'mbookmark.xml' file, located in 'user_email\Data' folder (using an user account). []

This is where it is when using SB Maxthon:

C:\Program Files (x86)\Maxthon2\SharedAccount\Data\mbookmark.xml (1202 KB, 2/8/2010 11:38:58 AM)
C:\Program Files (x86)\Maxthon2\XXXXXXXXXXXX@gmail.com\Data\mbookmark.xml (927 KB, 12/12/2008 4:01:22 PM)
C:\Sandbox\silat\DefaultBox\drive\C\Program Files (x86)\Maxthon2\SharedAccount\Data\mbookmark.xml (1200 KB, 2/8/2010 1:43:09 PM)

And ROBOForm still doesnt connect to fill in boxes correctly in the SB..

I can add Program Files (x86) folders to the built-in settings, but it will take a while before I release an updated version of Sandboxie.

For now, you will have to explicitly add your mbookmark.xml file (including full path) in the Full File Access settings in Sandboxie.

I tried that and it doesnt work.
I went to full access and added the full path.
Am I doing it wrong?

So what did you do, exactly?

Please give me exact directions:)
