Yep, I am running bitcoin and not bitcoind.
It just launches, and doesn't give me my cursor back. Since the upgrade from 0.20 it has done this. 0.37 does the same thing. I haven't tried 0.38 yet but I suspect it will do the same thing. I wiped the entire config folder and it still did it, I reverted to 0.20 and the GUI launches no problem. I have taken to now running bitcoin as a daemon since the GUI isn't working for me so it is not a huge deal but I find it odd/curious. None of my other machines (FreeBSD, Linux, MacOSX, Windows) have any similar issues.
