Maintain actxserver handle during clear

I am working on developing a Matlab interface to a external program using activex controls. I have got everything working, but have one annoying issue. Whenever the user clears the workspace, the application shuts down. While there is little risk of data loss, restarting the program is an annoyance due to acquiring licenses.
So, is there a way to prevent this from happening? One possibility is to overload clear so that it deletes everything except for the server handle. However, I don't want to overload a base Matlab function. I will also be distributing this to coworkers, so I would rather not require everyone to use clear -except when working with this interface. Is there a way to mark a variable as undeleteable during the basic clear operation (i.e. the only way to delete it would be to write clear var)?
Thanks.
