It would appear to me that the quality of 1Password has been declining; used to be rock solid and with the last two versions it keeps crashing on opening quite frequently. Sometimes it gets caught in a loop of sorts where it crashes before you can respond to the submission of the bug report.
If I were to put a finger on when the product seemed to have declined, Id say its with the web version release; Mac version crashes, iOS version crashes and the Windows version appears to be an afterthought.
