Since it only takes a few minutes I've lodged a bug report & voted:
http://harmattan-bugs.nokia.com/show_bug.cgi?id=476
This seems like it'd be a quite trivial fix, so everyone make sure you vote.

I don't think we should bother with enhancement requests for the native 4Square client.
Already there seems to be way better 3rd-party options.
But whatever is built-in, should at least work reliably....

@cddiede
I included your summary of the problem in part of the report, I hope that's cool?
If anyone thinks I've missed something, then please add your comments there.
