oops, I was just irritated

Now I understand, what happens, how to recover,
and what may be improved to not irritate the user.

1. pasted 1 st block. 
2. evaluates 1st block 
3. pasted block 2
4  clicked on evaluate of block 2

Since I was able to click on 'evaluate' on the second block, I (and several 
students)
incorrectly assumed that it would execute. But the second one will not run 
before the first one 
is interrupted by 'Action/Interrupt'

So is it possible to illustrate it better (yes, I know, there is a red line 
on the left side of the first block) that the 
first block is evaluating?

I propose that it should either not be possible to click on 'evaluate' of 
the second block until there is another block running.
or it should be at least printed "#waiting for evaluation of block 'xy'" ?
