It's possible Bitcoin ran and bailed out because something was wrong. debug.log should tell something if that was the case. What OS are you using? I wonder if we need Admin privilege and don't realize it. Stuff that requires Admin can't start on startup on Vista. Program shortcuts have multiple tabs of settings with lots of little details. I'll try the startup folder code and see if I can reproduce the problem. Every other systray icon on my computer is in the startup folder, and it makes it easy for users to manage all their autoruns in one place. The things in the registry key tend to be devious hidden bloatware. I implemented the code to flush wallet.dat whenever it's closed so we'll be able to tell users they only need to backup wallet.dat. You can restore just wallet.dat and it'll re-download the rest. I'll have to do another stress test before release. mmalmi@cc.hut.fi wrote:
