During the install of at least the last two prerelease versions of PD (1910 & 1918), my Finder relaunches. It happens after the install completes but before the final window with the close button appears. This is very annoying, particularly since there is no warning in the installer that this will happen or why it is necessary. Is anyone else seeing this or what causes it? MacBook Pro 17 Mac OS 10.4.7
