Test Execute is hanging for ever when it doesn't find what is expected

Considering that, based upon a previous thread, this is the first time, really, you're running theses tests on the VM as scheduled tasks, I'm not entirely sure that we can point to the version of TestExecute/TestComplete.

As noted above, you're going to have to spend some time debugging your tests to find out where the hang point is.  You might need to sit and watch it run to see if you can figure out where it's happening and then do some examination of your tests to see what's going on.  Again, the my main suspect in this is some inability to find an object that is resulting in a long wait time in object recognition.  

Is there any way you can run your tests in segments?  You know.. enable tests 1-3 and run it.  If it runs, add tests 4-6 to the run, and so on, until you get it to hang.  That should then target where the problem is and you can work on debugging.

Question: Is this a web application you're testing or a desktop application?  If it's a web application and you notice TestExecute is hanging, have you checked to see, via Windows Task Manager, if there is an instance of your web browser present in memory that is, itself, somehow hung?  If so, try killing that first before you kill TestExecute and then wait a bit and see if TestExecute exits on its own.  If it does, it should write out a log and you should then be able to see where the fail point is.
