I'll have a look at it, I haven't experienced that. Next Skill has to be used somewhat carefully because if the next skill cannot be cast, it will wait about 4 seconds before timing out.

Edit: If you're using one of my profiles, there is a value of 8 on the "secs passed" field on summon that may be what's causing the issue if summon is being repeatedly cast for some reason.
