Hmm weird, I'm testing it on four devices and on all it works fine. Aren't you using any special feature?
Anyway I don't have any older versions, because I remove them when new is created. Really, if you have such problems, and I'm sorry for that, please install working version from Google Play. Peter wrote me about something like this a few hours ago, so I hope this happen also on his device, so I'll be able to find this problem and fix it tomorrow morning. If so, I would like to release tomorrow new version ...
