Developers are saying it is only with your system. check your system configuration. But compared with my collegue there is no change in my system configurations. What is the reason?
Although, at first glance, there may not appear to be any differences between you and your collegues machine, there is obviously a difference. If the machines were identical then they would give identical results.
If everyone else is seeing the messages, then the developers are probably right in this case, it is likely a system configuration issue.
I would contact your sys admin and see if they can figure out what setting is different. That is what they are trained for.
9 out of 10 people I prove wrong agree that I'm right. The other person is my wife.
