Hi,
If you explode a block, the entities will generally return to the layers they were originally created on. In this case, turning all of your layers on and regenerating your drawing might cause the entities to show up. Zoom-->Extents can also be tried.
Another possibility is; the block could be a 3D solid and upon explode, change the view type to realistic and verify.
If this doesn't resolve the issue, can you attach a sample drawing file here or E-mail at sridharDOTsubramaniATautodeskDOTcom Let me know which block is causing the issue.
Thanks,
