Can you grep the glsel? It must somewhere inside your code, or base library
or addons. It seemed a form was not psel before glsel its child, not sure
why :: did not work.
I remembered the ctrl-z/escape/erase file had also happened to me. However
undo is implemented in j.exe and thus cannot be fixed except by Eric.
Please correct me if I am wrong here.
