DELETING TEXT FROM PC ON PHONE CHANGES DEFAULT SMS APP

[gingernob2003]

HI, I USE MYPHONEEXPLORER extensively and very very happy with it except when i delete a text on the pc app, when it attempts to delete it on the phone it asks to change the default sms app. but i have 'simply text' app installed and from memory it was suggested by you to use this sms app to avoid this. am i missing something obvious? as i would like it not to keep changing the default sms app and then leaving me to make 'simply text' the default again, once finished.

Thanks
David
