Uploading problems (Linux and Win98)

Hello.
I have the script that display the HTML form
(with file and text fields).
The problem is:
When I'm uploading images from Netscape on Linux - all fine, images uploaded ok, text stored in MySQL database and etc, and I can see the results by the scripts that display the database records and images.
But when am uploading from IE on Windows - the problem begins.
Text stored in database, but images uploading with some strange results.
filesize - ok, but in file - something strange, cuz images cannot displaying.

may be I cant upload bindata and text at the same time on Windows??

Please help me if anybody had this problem before.

I am using Apache 1.36 with php3 and MySQL.
Images stored on filesystem, and their filenames stored in database

Romik.
