# To subscribers of the xforms list from Jean-Marc Lasgouttes <Jean-Marc.Lasgouttes@inria.fr> :
Hello,
We got a purify (a memory checker tool) report on LyX, and I suspect
the problem is located in xforms. What kind of information could I
give to help debug this? Fell free to ask for help to decipher the
reports.

Subject: Sorry, guys - Purify report
Sorry,
one of our students included a couple of figures in his lyx document, resized
the eps files and the like. During one of these operations (we do not know what
it actually was) the following reports occured. Any idea?
Michael
PS: Thank god, Lyx didn't crash. But nevertheless it doesn't look good.
