DO NOT CHECK THE LICENSE EVERY SINGLE TIME!!!
Every time drawboard loads it tries to check its license. On a slow or limited internet connection this makes the application essentially unusable since its initial load time depends on a response to its license query. There must be a way for the application to control its subscription system without bottlenecking its load time like this. The irony is we would deploy the application more broadly if it was better designed. Drwaboard's approach to license control insures it sells less of them!
