I am experiencing a problem of invisible mouse-cursor on a VGA screen. Is there anyboudy out there having any idea about the source of the problem? The relevant details are: The program is written in TC2.0. It accesses the mouse driver directly via int 33. It runs perfectly on: - an XT with a hercules display card, - an AT with a hercules card, - another AT with EGA. It runs, but with an invisible cursor on: - a Compaq 386/20 with VGA. The mouse driver on the Compaq&VGA is Microsoft V5.03. An old version of Smalltalk-V I have shows the same symptom. When running Smalltalk-V in EGA mode on the VGA, it works fine. The code in my program is essentially this: initgraph (&GraphDriver, &GraphMode, ""); /* from TC2.0 BGI library */ reset_mouse (); /* does interrupt 0x33, AX=0 */ set_mouse_cursor_shape (); /* uses int 33, AX=9 */ show_mouse_cursor (); /* uses int 33, AX=1 */ ... The BGI package requires some display driver to be present, and it is. (both HERC.BGI and EGAVGA.BGI were present in all tests). --- Any clue will be most appreciated. - Ofer Faigon TEL: +972-2-669-834 MAIL: P.O.B 7347, Jerusalem 91072, ISRAEL BITNET: oferf@HUJINIX CSNET & INTERNET: oferf@shum.huji.ac.il - Ofer Faigon TEL: +972-2-669-834 MAIL: P.O.B 7347, Jerusalem 91072, ISRAEL BITNET: oferf@HUJINIX CSNET & INTERNET: oferf@shum.huji.ac.il
