move buttons inside group

Can not move buttons inside group in User Tool Window. They move chaotically and leave space that there is now way to eliminate.

Can you send me your config files?

Here is it. I just experiment a bit and looks like in that free space there are some hidden or undelited buttons. Because I just made some window and in group there was free space but after I restart NVil the appear buttons.
 

I just tried today to move buttons and looks like everything is working, no any free space and hidden buttons all buttons are moved freely. Do not know what it was if it repeats I'll let you know.

Today this bug appears again.
I notice that it is after removing button. It removes button but looks like it stay but in hidden state. After restart NVil this hidden button disappears or even appears.

I have seen that and various other problems with user buttons. But I think they are problems just on 64 bit OS.
I have hoped for quite a long time that a better implimentation would be made.
(Also to have the ability to make buttons custom colors, and not have to use the "Dock Caption Sceme" for button colors, that does not work correctly anyway)

I notice that these bugs with buttons appears after you copy group. After that you delete button it will stay in hidden mode and after restart it will appears.
