Works well for me. I clicked the Verify button
and it spins then says:
Hmm, are you saying that you did the following:
I clicked Verify button and i don’t see any compile button in the Web IDE 
It worked for me as described above
For completeness:

Weird. Maybe it’s the internet here or something.
FYI - I’ve been experiencing the web IDE locking up often, usually after adding or reimporting a library. I can refresh the page and the Web IDE reloads ok after about 45 seconds. It’s frustrating and slows things down, but until things get sorted out I don’t mind hitting refresh when I need to.
FYI I’m using Firefox 38.0.5
That’s when I’ve been noticing it too (should have mentioned that). I’ll import a library, then try the steps above, then it locks up.
Sorry about that. Could you guys try again now? The issue should be fixed.
Seems to be fixed! Thanks man!!
