try
code:
{
{
oddbobjectptr objtext = p->textid.openobject (oddb::kforwrite );
objtext->erase();
}
redrawwindow() ;
}
this should close the text entity before redrawing the window. may be leaving it open is the cause of the problem.

sorry - i think your text should be properly deleted now - may be some error in the rendering machine. what happens if you close and reopen the file?
