I can launch XP but once inside i get dialog box "Windows Explorer has encountered a problem and needs to close" then i have the option of sending the error or not sending the error to MS. it does not matter which of those selections i choose for it just continues to happen, rebooting, error again in same place. i have not installed anything knew and have rebooted the mac. the details i have discovered from the "Error Signature" are as follows: Error Signature: explorer.exe Mod Version: 12.0.4518.1014 App Verision: 6.0.2900.2180 Offset: 00075ac7 Mod name: msonsext.dll any advice?
