Reveal what EMM386 you are using (regrettably DESI-III requires EMS IIRC) 3. Other stuff (driver, TSR) present ??? 4. Free more low memory (frustrating low memory wars ... I hate them) or EMS page frame size This is most like related to the low memory hogginess of DESI-III and the EMS usage :-( Of source, porting DESI-III to 32-bit DOS (WATCOM FORTRAN) would be a great thing :-) > Is it possible do run a test without any mouse driver installed?

IIRC you can't even exit DESI-III with the keyboard (this is a BUG ...) -- ~~~ wow ~~~ ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
