ERROR: bad VLisp request: #2573

This happens when loading /Dev-Load1-Proj.lsp from Startup Suite:

Loading H:/uMill/dev/Dev-Load1-Proj...opendcl
Command: Application ERROR: bad VLisp request: #2286

loads fine from VL project.

The error msg was generated because dcl-Project-load was called
in a dwg with those forms displayed. Closing those forms first eliminated the message.

Can someone point to a discussion on cleaning up OpenDCL session between drawings. Also using OpenDCL with MDI.

Thanks,
Jim
