In file event-list.c function add_el_row there is no check for XFICAL_FREQ_HOURLY; and the default flag symbol is 'n'; with the result that hourly recurrence shows as 'n' which of course should mean no recurrence. Would be good to add case for XFICAL_FREQ_HOURLY (as 'H'?), AND to make the default flag be something else such as "?". In addition, it would be good to update the hint message to document this. This is a really easy fix. -Ted Merrill
Yes, this seems to have been forgotten. (After adding this, the default flag is ok. N=Not repeating)
This is now in Orage 4.9.0.0 in git. I also fixed alarm flag and tooltip as those were badly wrong. Thanks for a very helpfull bug report.
Fixed in 4.10.0
