Graphics glitches
If you're experiencing problems with long load times during which the screen is blue (but which clears up after a few minutes), please be sure that your computer meets the minimum specifications, most importantly having at least 256 megabytes of RAM, preferably at least 512.

Most problems with graphical glitches, blue regions of the screen, invisible pirates, and missing buttons and panels are caused by missing or corrupt files in your local Puzzle Pirates installation. To solve this problem, use the following instructions:
 * Windows: Download and run the full installer from http://download.threerings.net/yoclient/puzzlepirates-fullinstall.exe, making sure to quit Puzzle Pirates once the download finishes but before you run the installer.
 * Mac: Close Puzzle Pirates, delete the Puzzle Pirates application, then download and run the Mac installer again from http://www.puzzlepirates.com/yoclient/yohoho-install.dmg.
 * Linux: Run rm -rf ~/yohoho assuming that you installed Puzzle Pirates in ~/yohoho. Then, re-download and run the Linux installer from http://www.puzzlepirates.com/yoclient/yohoho-install.exe

If you continue to experience problems after reinstalling Puzzle Pirates, please report the issue here.
