[BUG] Strange grouping

Steps:

1. I made 3 groups of objects

2. Press ctrl+d to duplicate.

3. Try to move objects down or up (ctrl + arrow)

 

 

Is it normal that I have other group between 2 looking like one group.

Moving objects up and down always making mess in design process because they are connecting to groups on their way up or down in objects panel.

I read  some posts suggesting that 32bit version has less bugs than 64bit i'm using?

Is it true?

Anyone there testing apps? Looks like nobody tested photopaint X6 before it was released.

I didnt need too much time to find bugs working on my webdesigns in photopaint few hours per day.
