Now into my second month of working with HP QuickTest Pro and Quality Center in my software QA job, the most annoying bug that I have run across is QTP's tendency to lose track of its connection to Quality Center for no apparent reason.

This happens when I am running test cases stored in Quality Center locally through QTP. It can manifest itself several ways:

* When saving your edits to Quality Center, a "General Error saving the test" message.
* When saving your edits to Quality Center, a "Save As" dialog appears which is useless because you cannot overwrite a test in Quality Center. You can only save the test locally, which is also useless because there is no way to get that saved test into Quality Center without losing history.
* When running a test that references a function library stored in Quality Center, an error message says the function is not defined.

When this happens the only option is to reload the test from Quality Center and lose any changes you may have made. But the next time you edit or run the test locally, it happens again.

I haven't found a pattern to it yet, but it seems to come and go. Once it starts, it happens every time you run or edit a test from QTP, you might as well call it a day, you aren't going to be able to edit or run from QTP.

This bug is inexcusable, and makes using QTP and Quality Center together much more difficult. It almost defeats the purpose of using the tools together. But I have no choice about that in my current job, so I soldier on as best I can.
