Almost every time I open a PSD file most of my text layers have the triangle exclamation mark next to them. When I edit the text layer I always get this warning message.

====================================
!
Editing or rendeirng the text layer "abc" will cause its layout to change. Continue?
[OK] [Cancel]
====================================

If I update all the text layers, save the document, close it, open it back up again, the text layers require a layout change again.

Any ideas why this is occurring?
