After the update to JB I have noticed a problem.....not huge..... but very irritating. When trying to enter an event on the stock calendar, after you have entered all the information and press SAVE, it may or may not save it. If by some slim chance it does at least save the title, the details you wanted are not there and the edit function is absolutely useless.
I researched it and tried all the tips and tricks (reboot/clear cache/etc) but nothing works. I finally resorted to entering events using the ADD QUICK tab which enters only the title.
Looking forward to a fix for this.......
