I can't comment on the specific question, however I do use several other ActiveState products, and most of them are very stable and solid! They also have a very good support group that is quite helpful.

I realize this is not an answer directly, however, when evaluating tools it is nice to get references on the company building these tools. ActiveState has done quite well for what I have used them for, I give them a ++ :)

"Nothing is sure but death and taxes" I say combine the two and its death to all taxes!
