Spell checking while typing

I have the spell checker set to US English and to check while typing in v6.0.19714.0.

Frequently the red line will appear under a few letters of a word I’m typing, even before I hit the space bar to type the next word. The red line does disappear if I spelled it correctly.

It’s not a big deal but I’ve never had a spell checker behave that way. They have always waited until I’ve hit the space bar to check the whole word and then underline if necessary.

I don’t know if this is common or just on my computer, but maybe eM could wait until I finish the word?

Hi, this will most likely not be changed, I understand that it is not comfortable for everyone but it is not thing which will prevent smooth workflow.
