- I am having a similar problem with the text cursor. When I write
- under the cursor, either with BIOS or directly, moving the mouse, reveals
- what was previously there. Also scrolling with BIOS moves the mouse
- cursor, actually makes a copy deleting the cursor which appears when
- I move the mouse.
-
- It has occured to me that interrupt0x33function 0x0B, can be used with
- int 0x33 function 0x03, to write my own routines to control the
- cursor myself. But I would have to poll it constantly, and intercepting
- int 0x21 wouldn't help because than I would have to write the whole
- driver from scratch. So the function would just have to have a
- polling loop.
-
- The same solution would work with a graphics cursor, but so much work to
- implement!
-
- Does someone know if there is an easier way?
-
- HELP!!!!
- Thanks,
- Mitch Dernis
