Premiere Pro is not working correctly for you. Whether the problem is insufficient hardware, corrupt software or operator error can't be determined by your posts, so it is difficult to offer constructive help.

One issue that really concerns me is following
Move from editing to graphics, do some changes, move back to editing, there is a good change that your sequence disappear, and trying get it back from the project works with exception that their are now no audio lines and can't be restored
Unquote.
When this happens:
Step 1 - go to the menu Window> Workspaces > Reset to Save Layout. Does the timeline appear?
Step 2 - in the project panel, find the sequence you were working on and double click on it. Does the timeline appear?
I'm not sure what you mean when you say:
and trying get it back from the project works with exception that their are now no audio lines
If you post screen shots of what is occurring and what you are doing, it is likely someone can help you figure out what is wrong.
Also a complete hardware description, and a description of the properties of the media you are working with would be helpful.
