LiveCode won't recognize my stack

Richard and Brian,

I think you guys are on to something. The LiveCode open dialog filter is a different issue than actually being able to open the file as a stack. Thanks.

For some reason my OpenStack handler in the Card script isn’t being triggered. This is causing a number of issues including failing to “start using…” some library stacks and the one I reported here.

I’m looking into that now.
