I use icalx.com to host my calender and see it remotely (me and my girlfriend share it)... I put my schedual in the calender as weekly events, classes Mon, Wed, Fri repeating till spring break. Then I copied the event to after the spring break and told it to repeat again, Mon, Wed, Fri (no changes) to the end of the semester. close sunbirg after it asks for my user name and password when i logs in. Open sunbird back up, The Original event (before spring break) is there, but not the second event. I ended up having to create a whole knew event and re-enter all the information and tell it to repeat. This happened for all five classes that I did this too. Reproducible: Always Steps to Reproduce: 1.create an event starts at 9:00 - 9:50 goes from Jan 8 to March 5th. Have it repeat Weekly, Mon's and Tue's. 2. Then Copy Feb 28th to March 12th. Tell it to repeat till April 25th Mon, Tues. Actual Results: After all these steps are performed, the "copied" event from March 12th to April 25th (after closing and reopening program) is GONE, its just not there. You have to Create a BRAND NEW event (CANNOT COPY) in order to get it to save. Expected Results: All events would have been there through there repeated dates. *Note, I only use remote Calenders using icalx.com, may or may not make a difference, I wouldn't think it would. ** I am also using an Intel Mac (10.4.8) and I do know that Sunbird is only written so far for the Motorola processor, and is using rosetta in order to translate the code on the fly. So, that also could be an issue.
