This is an example of a very common bug with TC++, which involves all types
of mouse drivers.  The problem is caused by calls that TC makes to "new"
mouse functions which were not supported by "old" drivers.  In the new
drivers, the mouse cursor position and type can be saved and restored by
programs, which is what TC++ is doing.

In nearly all cases, a driver update will fix the TC++ mouse problem.
My mouse is a Microsoft PS/2 mouse version 6.11, and Borland says that
I need a newer version.  I just contacted Microsoft and requested a 7.04
mouse driver.  They popped it in the mail the same day.

Hope this helps with your solution.
