Hello Jon,

Thanks for your answer, sorry for the delay.

I think one of the problems I'm having is that I'm confusing
synchronous calls of erlang processes and the actual process of the

I was wondering if I make a synchronous call from a wx process to a
gen_server process (using gen_server:call for example) if the whole wx
application would block. For example, would I be able to click a
button mean while the call completes?

I suppose that depends on the application, wouldn't it? I mean if I
spawn another process to call gen_server the wx wouldn't block.

I'll see into it.

Thanks again for your answer,
