Hi,

No problem! Should've expected that, given I'm using alpha version.

I have one extra question (forgot to include it).

I noticed that, when I pin some object (in my case it's Form's bits) 
that I'm about to pass to FFI call, the call fails with "could not...". 
However, the call succeeds when called again with the same object.

When I don't pin it, the call succeeds the first time.

Could you explain it?
