1-)Is it possible cancel focus change via wheel? 'cos on mac touchpad, double finder move mean scroll to x or y direction. 2-)page tabs moveing sometimes unwanted style. I could not find yet how to, which key combination or etc. some times click to tab for activate it but, change position (pageindex) change.
3-)Click lock 2-3 pagetab, then if try open new file (tab) IDE open new source editor

You mean "lock" from context menu (pop-up)?

Are you sure, the file you are trying to open (that gets a new window), is not one of the files, that you locked?
If so, then that is expected behaviour.

"Lock" means the IDE will not scroll the editor in this tab, if you try to jump to an identifier, that would need scrolling, then a new window is opened.

Yes

long time been, I forgot how todo this, I tried more time but work normal now. I'm sorry not tried before write one more time this.

If you mean, not scroll is can not down/up in editor, its not work like that for me. I mean, I can scroll down/up and can edit. When cmd + click on procedure name, its jump and if its not opened file, file is opening and goto procedure definition. At this point, lock and unlock not different, just tab caption has '#' symbol

In my mind, lock tab mean, tab is always opened, and cant change page index and cant close.

"Lock" in the source editor means, that it will not scroll by itself. (e.g. as a result from code jump actions).

It does allow scroll by user.
