Input Validation Message vs. Calendar Widget

Hi all,

I'd like to know your opinion regarding the use of Input Validation Messages with Widget Libraries' Calendar Widget. The problem is that the input validation message «kicks» my calendar widget aside :(
Have you noticed this? Do you think it is okay? On the other hand, I think the current calendar's positioning (on the right side) is pretty fine. What do you think?

Check out a sample in attach and try out yourself.
