I haven t had a look at CTMOUSE sources yet, but I will for sure when 
I find the time (currently I m using the LOGITECH 8.something LMOUSE 
driver because it supports CLOAKING to reduce the real mode memory
footprint of the driver downto 1 Kb). 

I have a suggestion for CTMOUSE to further reduce the real-mode
memory footprint. If data is not embedded into the code it should
be possible to adapt it to support DR-DOS (and PC DOS) DPMS (DOS
Protected Mode Services) leaving only a stub in the 1st meg.
The DPMS SDK should still be available from Lineo for money, 
and shipping the DPMS.EXE driver with CTMOUSE would need licensing 
and also not harmonize well with the GPL, of course. 
However, supporting DPMS in applications is, of course, not subject 
to licensing. The DPMS API as it was publically and freely available 
from Caldera s web-site back in 1997 (excluding example sources 
etc.) should still be downloadable from ftp://ftp.lineo.com/.
Ralf Brown s INTER61 also briefly lists the DPMS API.

Regarding any possible problems under TASKMGR (again, I haven t 
tried myself yet), hence I m guessing here, but it might be required 
to declare some of CTMOUSE s data areas holding status info (such as 
state engine data) as instance data. The API is identical to the 
Windows startup/exit broadcast API at INT 2Fh (see INTER61 as well). 
There are also some TASKMGR.INI directives to declare whole drivers 
as instance data "from outside".
