I’m very sorry about this, but there’s a bug in HippoRemote Pro 3.0.1 that makes the top row of buttons (keyboard, settings, and profile selection) unresponsive. This issue affects non-multitasking devices — the iPhone 3G and iPod touch 2G — and can happen when the app automatically reconnects to the last computer on startup.
A fix is coming very soon. In the meantime, there is a workaround — Switch away from the trackpad screen and back again. This is obviously harder to do when the main buttons are not working. If the profile you’re on has a button for Macros, tapping that and going back will work. Or, you can bring up the shake menu (by shaking your device) and tapping on Logins or Web.
Again, I apologize for missing this bug and ask for your patience as I push out the fix.
