We use the latest version of Lens Studio (1.7.1).
Start Lens Studio.
Then you can load a project, or not load anything, the following bug is the same.
Exit from Lens Studio.
Open the Windows Task Manager, look in the "Processes" panel, you will see "Lens Studio.exe" is still here (it doesn't use CPU, but it keeps memory).
Start Lens Studio again, exit, start, exit, etc...
You end up with several Lens Studio processes at the same time.
Our GPU : Quadro K2200
We use Windows 7 Pro SP1, which is unsupported by Lens Studio.
Is this a known bug ?
