Copy Text into Draftsight

dear draftsight user,

I have a problem about enterprise draftsight in our customer, which is not able to copy text from notepad and ms word, for more details, I include a video on the attachment.

has anyone experienced the same thing as that?
because in draftsight free, copy the text can still,
maybe anyone have a solution?

Thank you so much for your help,
regards, 
SA,
