I have that same problem. Today is 11/28/03. I downloaded Xolox v1.57 build 768 to my hard drive. When the program opened it worked fine. When I went to close the program, multiple windows opened with an unknown closing error. One of those windows contained the following message:

Exception EAccessViolation in module XOLOX.EXE at 0004F417. Access Violation at address 0044F417 in module 'XOLOX.EXE'. Read of address FFFFFFFF. Exception EAccessViolation in module XOLOX.EXE at 0004F417. Access Violation at address 0044F417 in module 'XOLOX.EXE'. Read of address FFFFFFFF.

This happens every time Xolox is closed. I am using a computer with the following:

Windows ME operating system
1.3 ghz processor speed
40 gb hard drive
256 mb RAM
CDROM Drive
CDRW Drive
Floppy Drive
AMD Duron Processor
Motorola SB4200 SURFBoard Cable Modem

If someone out there has an answer to this problem, please reply to this post.

Thank you,
