MSCDEX and Windows '95

I have discovered something strange in a DOS-box under Windows 95 :

Normally my code to control my CD-ROM player works great, but since
Windows 95 it won't work anymore. For the control I use IOCTL. Windows 95
reports in a DOS-box that MSCDEX 2.95 is loaded (and won't allow to load
MSCDEX 2.23). Everything worked great under MSCDEX 2.23, so I don't think
it is a bug in my code.

I hope somebody has a sollution for me.
