Hi
TestComplete should only capture the images you are recording. If you are recording steps on a web application and that web application opens on the main monitor, it will just record those steps.
Please do the following.
1. Open TestComplete in the main monitor
2. Open the application you are testing in the main monitor
3. Record a new keyword test
4. provide the test visualizer screenshot output to this thread
Do steps 2-4 above but keep TestComplete open in main monitor.
Also please review http://support.smartbear.com/viewarticle/70760 in relation to running tested applications in TestComplete. I would also recommend running TestComplete as "Administrator". right-click on TestComplete icon and "Run As Administrator"

Damien
