Dear Mister Simonic, ouer Institut (TEMF TU-Darmstadt, Schlossgartenstr. 8, D-64289 Darmstadt, Germany) has buy 25 Licenses of TEX. We have changed from Windows NT to Windows 2000. With Windows 2000 TEX only works with Administrator-rights. Is there any Update for this Problem? I hope to hear from you soon. With best regards, M. Dorn
