Its up to you. All inputs from all users are always welcomed if they have some value at the end.
If you'll put information how to reproduce bug, attach logs if needed, answer additional questions without asking to be paid you're surely welcomed. That's what most clients do.
In case you don't have time to check your settings and provide more info, you can start with Questions section where you can get information why something may not work.
Youre not newbie here.
What is my vision in bug thread. I'm noticing bug (check all my bug threads and you will see that when i report but then 90% it is real bug and not something i did not understood, as you said i'm not newbie here and working with ZP every day and full time) then i report it without any deeply investigation.
Then thread goes live and we can wait any other input from other users. If we see that other users reporting same bug then it is more that clear that there is some global problems.
If other users are silent then that again do not mean that there is no bug and you can not change thread status to [SOLVED] because it is possible that there is some bugs related to your PC configuration or win you use. As this was with some bugs in past. Example:
http://zennolab.com/discussion/showthread.php?5443-Dissapear
Also it is possible that my reported bug appears just once because of some errors in program itself, but again it does not mean that this is not bug.
In all cases it is totally waste of time to jump in and investigate deeply after first time this bug appears. And also it is waste of time to answer on all your standard questions... As i checked in my bug threads before could not find that you helped to resolve many of them.
What next: when i'm noticing same bug again i'm going back to my bug thread reporting that this bug repeated in bug thread and starting to investigate it deeply and going over to direct conversation with DD.
I would suggest you to take care of newbie questions. And give your input in my bug threads if you are sure what would be problem. This will be more valuable from you. You will have more time to answer other questions and also i will have more time to find other bugs and help to make Zenno better.
Nothing personally as usually but this is my point and i'm my view is that this is right way to help each other.
