Accessing the Development Center
Normally, the _ZimPROF document (provided with your software) that is run when you start running Zim, invokes DC automatically.
However, if you have your own ZimPROF document, the _ZimPROF provided with the software is ignored and the DC is not invoked automatically. If you wish to restart the Development Center, you can enter (at the prompt)
If you launch Zim without any parameters, you see the DC window immediately. Once you close the DC window, you see the backscreen displayed. If you would prefer to see the backscreen displayed immediately, then create an empty ZIMPROF file before invoking Zim.
