Material Editor

[Dantess]

Hi all!!!
And a great thank you for Amnesia and the toolset.

I have a question. Maybe the problem isnt one but i ask.

I make some material with the editor, and when i reopen it or use it in the level editor, the mat file is empty, like nothing where saved.

And another one, still with the material editor, sometimes, when i try to open a folder in order to choose an image file, the editor doesnt work, it simply shutdown, trying to send an error file to frictional.
Is it normal? (for the bug, not for the error file)

Thank you all!!!
