Overset text box question

All,

I upgraded to CS6 from CS5.5 (windows 7-64)

After opening a indesign 5.5 document in 6.  Many of the text boxes become 'overset' when trying to alter the text with in the cells etc etc.

Also, deleting or find and replacing the text also changes the box to overset. 

Just as strange, even trying to re-size the box creates the overset.

all I did here was drag the corner

Has anyone else run accross this?

any ideas on how to fix or work around?

PS: tried the file on multiple machines with same results.

thanks
