EM Client closes to task bar

Whenever I add a calendar event or send and email, EM closes to the task bar? I have not selected EM as my default email as I am still testing all the features. Would that be the problem? It is a pain as I have to continually re-open the program to continue working with it. Maybe there is something I missed in the settings?

Appreciate any response that would provide some detail on this weird situation.
