If your FTP
client relies on Wininet and supports resuming of downloads then it fail to
work under IE7 because RETR command is not working properly when you invoke it
using FtpCommand(…) function. The
function fails with access violation, outputting the “0xC0000005: Access violation reading location 0x00000001” message. The problem was
reported in wininet NG by Noël Danjou
and I believe it will be fixed soon by WNDP team.
