I opened an SMA product with 10 parts in Part Properties. All I wanted to do was rename Part_1 etc. The text entered fine in the formula box and changed the field in the editor window but the names in the Parts List never changed while I went down the list.  After completing line 10 I pressed Save, Close & Redraw which brought up a Fatal Error and locked-up Tbox. Coming back in everything had been saved and the product processed normally. 

I haven't seen simply typing text in Part Properties cause so much trouble. I backed up to 1227 for now. Has anyone else run across Part Prop issues with the newest build?
