Trouble sending attachments in GMail

[hbquikcomjamesl]

Today, on my lunch break, I tried emailing myself a file from my Nexus 7.

I could not get the "paperclip" attachment icon to respond at all. Either nothing would respond, or a nearby icon would respond.

This evening, I'm going to try it with a mouse attached.

Has anybody else had this difficulty?

This is weird: I tried it at home this evening (albeit with no WiFi around), and it worked fine with both a mouse and the touch-screen.

I'm definitely tossing an old USB mouse in the suitcase, this trip.
