>I have a customer using my Foxpro 2.6 application in Windows 95. All of a sudden, randomly, the mouse disappears. It shows up when she moves mouse outside of the foxpro window, but disappears as soon as she moves it back into the window. The clicks seem to work, if you guess where the mouse is, get lucky, and click on a button with your "phantom" mouse. Mouse works on other apps just fine. And I;m not turning mouse off programmatically. It JUST happens. Randomly.

I have seen this happen often on the machines I have at work. The usual cause
is when FP locks up for whatever reason and, using ctrl-alt-del to get the task
bar, shutting down FP. Though it doesn't happen every time, it does happen most of the time, yet the mouse works on the desktop and other areas. Sometimes, I can simply open another app (game or whatever) and, if the mouse is working in that app, I can mess around a little and then close down and go back into FP and the mouse works, other times it's "Start, Shut Down, Restart",
and I hold down the RT Shift key when clicking OK so the computer doesn't have to reboot but Windows just restarts. It seems that by shutting down abnormally by ending the task in the task bar severs something in FP to know there's a mouse. It's not only FP, when it happens, there are other apps that exhibit the same behavior. Another attempt at getting the mouse back using a Win 95 keyboard (one that has a "Windows" key to access the start menu) is to use the keyboard to get into the Control Panel, Mouse, and selecting the General tab then pressing the "Change" button to change the mouse driver but selecting the same one and letting it reinstall itself. When the window comes up to reboot, select "NO" and try. Maybe someone else has a more technical explanation, but this is my experience. Hope this helps.
