Sharing from Preview via Messages blocks Preview

When I share a picture from Preview via Messages then Preview is blocked while Messages sends. So, if I try to use Preview in that phase it’s unavailable to me and the Preview “blinks”. This is ok if I barely notice it. However, if the internet connection is bad (like sharing the 3G/4G connection from an iPhone 5S with the laptop in a cabin up in a mountain) then Preview hangs or waits for several minutes before it gives up and tells me. I cannot proceed with viewing other pictures in this phase. It’s “formally” the “green” type of blocking (*), but since the solution really blocks all of the machine since viewing pictures was all I was going to do, I’d say it’s almost “red” blocking.

Is this some error or is it by design?

Yes, both of these replies are fine (Messages doesn't seem to block when it's "alone").


However, my case addresses the fact the Preview blocks while using Messages; from a computer science perspective, in my view, this is questionable (=bad) design. However, it may be some error in the code, but as a programmer myself I find it less probable. It may also not be per design, it could be some side effect during some particular loss of connection, but I also find that less probable - because I can see the "blinking" of Preview for some seconds (if I press it) when I send a large picture in all cases. Initially I tried to set up a case to show how it might work.
