"Individually sold" product property not working with this plugin

Hi,

Thanks for this nice plugin. However we’re having an issue with it.
When this plugin is active the ‘individually sold’ product property does not work anymore.
Ticking this property normally ensures the client can order only one copy of a certain product (choosing a quantity is disabled). When this plugin is active, the client can still choose a quantity, which is not what we want.

Is this a known issue and is there a solution for it?

Regards,

Hans Driezen
