Purify Bug?

[dsa]

When I purified something, and then, while purifying, casted a spell, then the window where you purify in disappeared and didn't ever open again. I had to restart PS to fix it.

which window? there are a few windows involved in casting a spell and purifying a glyph. A little more information might help us determine if this is a bug or if you did something wong. possibly you could have also moved the window off the screen and it came back when you relogged.
