I see you understand me perfectly :) Also I couldn't agree more with your opinion related to community work.

>Thanks so much for sending us your tests, it is a big help !
By the way I indeed have couple ideas how to make testing process more effortless but I need a little bit more time to think about it.
Just trying to make sure that effortless's ideas don't suggest something really stupid or not practical :)


Thank you,

Vladimir

Glad to hear the resource was useful.

Following your advice I send description of my weird problem to the
quality email list.

Sorry that I didn't have time to prepare normal test case. That why I
asked early for effortless procedure :)

  

Regarding the other issue that I told you in email, looks like the
situation much improved now. I still will continue testing it to make
sure it's gone completely. I have quite different applications and it's
better to redeploy all of them to see if they continue to work fine
after redeployment.

  

Best regards,

Vladimir
