Multiline text Macintosh version

I just installed the latest Mac version 1R2.1 and now when I try to use multiline text, the enclosure field locks up and does not allow me to click for the second point to define the text area.  The crosshairs lock in place and the arrow cursor shows but I cannot get the second point located.  I have to hit escape to get out of the command.  I tried to use the command window to put in the second point coordinates as well and that also locks up.  This is serious as I cannot notate the drawing in any way.  I have tried multiple drawings and get the same results even in a new clean drawing file.  I am using a Mac Pro with OS 10.6.8.

Also, with an existing multiline text field, I cannot drag the defining lower edge of the text field window grip to resize the text field,  I can drag the grip up but when I release the grip it just goes back to where it was.  I cannot resize no matter what I do.  Again, I have tried many existing files and also a new clean drawing file.
