Thumbjam crashes on iOS6 in the MIDI Input section of the Preferences panel, can anyone confirm?

iOS and iPadOS
Hi, Can those of you who own a copy of Thumbjam music app please confirm the following? 1. Start Thumbjam on your device with iOS6 installed. 2. Tap "Prefs" in the bottom right corner, then select "MIDI Control" from the pop-over menu. 3. When the larger panel comes up, swipe through headings until you get to the "MIDI Input" or "MIDI Output" section. At this point Thumbjam on both iPad and iPhone crashes. Can anyone please confirm this behavior? If yes, can you please let the author know, at support at thumbjam dot com so it doesn't look like I am the only one with the crash issue? Thank you. Victor
