When I run Draftsight all works fine, but every time when I want to close the software by clicking the red x in the upper right corner, I'll get the following message

It says something like: Darftsight doesn't work any more and need to be closed.

So I was investigating a bit of time and could find out, that it is somehow connected with the "dataexchange.dll", this information can be found within the system information or in the Application-Log

Does someone has any idea what I can do to avoid this?
