After using Test and Lab Manager for a while, suddenly the Test Results View disappeared after some resizing. We tried everything to get the tab back, but repairing, re-installing, cleaning the registry, nothing did the trick.
Today a colleague finally found a solution. You have to clean the settings stored in the Local App Data section of your user profile. These settings are simple XML files that have your settings from MTLM – window size/location, whether the Test Runner is docked or floating, the queries you’ve configured in Test Case Manager, etc…
To easily navigate to them on Windows Vista, 2008, 7, or 2008 R2, open this folder in Windows Explorer:
%localappdata%\Microsoft\TeamTest\v10.0\
Or, on XP, 2003, and 2003 R2:
%userprofile%\Local Settings\Application Data\Microsoft\TeamTest\v10.0\
In this directory you will see a number of *.config files. They will be prefixed with ‘mtlm’. The main configuration file is ‘mtlm.config’ – the other files you see are isolated files for each of the activities within MTLM. Just delete all the *.config files in the folder mentioned above. You should do this while MTLM is not open, since we save your settings on exit. Once you’ve done this, you’ll start MTLM in the clean state you had it when you first installed it.
