When I try to download photos from my iPhone by using Windows explorer and treating the phone as a drive, explorer crashes. This happens on an Acer Aspire one, running XP. I have no trouble performing the same operation on my Dell Inspiron 5150 also running XP. Is there something wrong with the XP set up? I cannot see any difference in the set ups but I may not be looking in the right place.

Often, instabilities in Windows Explorer are attributable to faulty shell extensions and addons. Consider using Sysinternals Autoruns or ShellExView. Disable non-Microsoft shell extensions and add-ons, and check the behavior. If it is gone, re-enable the disabled extensions/add-ons, one at a time, and see if you can identify which may be responsible.Try a clean boot, or boot into safe mode. Does the behavior persist?If you continue to experience the behavior, since you're using XP, check the Dr. Watson dump folder for a crash dump with a timestamp that matches an Explorer.exe crash. Start->run-drwtsn32.exe and check the "Crash Dump" setting. If the timestamp of user.dmp matches, ZIP user.dmp, upload it to your SkyDrive, and provide a link.
