With the official 1.6 version I have still this problem on PC:

After the keybinding on standard with the beta-patch-1.6 the standard-R-key hasn't got the "take-all"-'function for items in vessels any more. Dito with any other key after changing. With the version 1.5 after repatching in the beta-phase, there wasn't this problem. Strangely this problem isn't with Septimes (moneyunit in Tamriel) but with the other items of Skyrim in vessels.

Is there any solution for this problem? (Since beta-phase of 1.6 I wasn't able to use any mods. So this isn't the problem).

I've rebinded that key to middle mouse button since i got Skyrim and it still works the "take all" function for me,maybe it's on your end? :/

1.6 resets your keybindings and .ini settings.

You should be able to revert to whatever you were using before by setting up the same controls configuration you did previously. If you are using a different button for Sheathe/Un-sheathe weapons, try that one, or try mapping "sheathe/unsheathe" to the "R" key.

I'm using "R" for both sheathe/unsheathe as well as "take all"

Sorry people. I'm so an Idiot. I must only delete the ini-files in the save-file. So my problem is now solved. I could annoying at myself the whole day. In the future I will never forget this method. Anyway thanks thanks thanks.
