I have to agree with Wil above, I can now resize and toggle in and out of full screen without issues, I have not tested the logging in with full screen enabled though.
Yes this is still an issue in 1.5
Update: the issue still seems to happen both on java 6 and 7, and can happen even on a simple window resize. its doesn't just cause Minecraft to lagg or crash but the whole mac itself until you can force quit or a forced restart. From my research i have only heard about this happening on retina MacBooks, however i may be incorrect on this.
Many Thanks
Daniel
Still happens on 1.4.7 on a macbook pro retina 15", it also happens when going fullscreen by pressing fn, alt and F11. It happens consistently and can be reproduced however can screen shot as the whole mac freezes.
After getting in a boat and travelling when exiting there is about a 5% chance the boat will teleport to where it was boarded. Once there it cannot be moved or interacted with unless the player re-logs or after waiting about 30 seconds in which the boat teleports to where it should be and acts as normal.
