Multiple VIDEOINPUT objects cannot access the same device

Hello

I am debugging some function that works with webcam, videoobjects.
If an error appears before finishing function, next run this function
gives following error message:

??? Error using ==> imaqdevice.preview at 181
Multiple VIDEOINPUT objects cannot access the same device simultaneously.

I have to stop video object, to release memory, but for the moment of
error any variable are not present in workspace.

To run function next time I need completely restart Matlab. Is it
possible to stop invisible objects without such restart?

Thanks in advance for ideas
