I've had three crashes so far since running 0.4.7. When the wallet crashes, it sends a report. But then I cannot open the wallet again by double-clicking on it. I have to restart the computer to be able to run the wallet. It's currently syncing, hopefully if it completely syncs then I wont have any issues.
Also, since I imported my wallet and it hasn't completely synced yet, I am not seeing a config.json file in the appdata/roaming/Bitshares X folder and without the config.json I cannot add the chain server. This might be an issue that needs looked at. Also some people are reporting the chain server is not working anymore.
