Question the Implementation

Environment:
Application: Windows application
Operating System: Windows Vista

Requirement:
Whenever Agent hits Button (say Close Call) ,the application should close the session and the same time it should generate an XML should store in a table.

Implementation: Whenever Agent hits the button instead of directly storing into data base application temporarily stores in local machine and then stores into the data base. Once application stores the XML in the data base application will delete the temporary file.

Repro Steps:
1.Launch the application.
2.Do some operations in the application.
3.Click on Button.(Close Call)

Actual Result:
Application crashes.

It happened only in UAT environment in all the machines and Testing environment it never happened. After UAT people reporting the bug ,we tried but could not repro it. After going through the log file we came to know that application is crashing while writing the data into temp file ,meaning application unable to append the data to the existing tem file because of some corruption and then it crashes. Then the implementation has been changed to like this
whenever agent hits the button ,before writing into temp files application deletes the old file and creates new temp file.

Finally ,what I would like to Conway is as a tester it's not enough to cross check the functionality with respect to document we also need to check (if possible test )how the functionality is being implemented.

CAP's Lock

Environment:
Application: Windows application
Operating System: Windows Vista

Requirement:
If agent selects the option save the user name /password ,from next login onwards application should not ask username/password.

1 .Launch the application
2. Save the option user name/password once you logged in with
3.Close the application and launch it again by clicking the short cut .

Actual Result:
Some times application is not doing automation.

As testing team haven't provided exact repro steps and moreover it happened in my machine only ,dev team set the priority as low.

I defiantly know ,there is some issue but I could not figure it out for long time why it's happening some times that to in my machine. That time I had changed my password as per the password policy ,mostly I will keep at least two letters in CAPs. Whenever I am entering my password I will on the CAP's lock, after login I will off the CAP's lock. That time I got the exact repro steps why this issue happening some times

Here are the repro steps

1 .Launch the application
2. Save the option user name/password once you logged in with
3.On the CAP's lock.
4.Close the application and launch it again by clicking the short cut .

Actual Result:
Application is not doing automation.

Reason: When ever we switch on the CAP's lock Operating system will display a message 'CAP's lock is on..' because of this the focus is not moving to the password field.
