Can Bridge be set to preferentially open files in 32 bit CS5?
Bridge CS5, when it doesn't crash (which seems more frequent than even CS4) opens images in 64 bit CS5 by default.
Most plug-ins are 32 bit so it would seem user-hostile for Adobe to lock down Bridge, which remains as randomly unstable as prior versions, so that images only open in 64 bit CS5 unless the 32 bit version is already opened.
If one uses the 32 bit version of CS5 preferentially it is pointless to have Bridge load automatically when the computer boots. If a Photoshop process is single threaded, which most still seem to be, the 64 bit version will not improve performance for those tasks no matter how much RAM is in the computer, something Adobe seems to be obfuscating but which objective tests demonstrate.
