Interface locked when converting items or doing desynths

Hi I play from PS3.

Sometimes, when I do a materia conversion (or a desynth) and before the animation I try to exit the GUI (press the circle button mor than once in a row to close all GUIs), the GUI gets almost locked:

- I cannot teleport
- I cannot Return
- I cannot Speed
- I cannot change gear or class/job
- I cannot exchange/delete items

the system says: cannot do this operation while dealing with items.

Solution: walk to a different zone

The good thing is that the equipment I was trying to convert or the item I was trying to desynth does not get lost.
