We have a client that teaches Gymnastics. They use Class Manager from Atlantic Associates to manage their class scedules and finances. Her computer (Dell Dimension 2400 w/XP Pro) works perfectly, but they said the computer freezes and the mouse goes hay-wire(pointer starts jumping around and if you left click anything it right clicks instead). We have tried to replicate this problem but to no avail. With all of the discriptions of the problems and the testing we have done it seems to point to this program. I have search everywhere I could to see if this program has had any similar effects of other computers. I am just wondering if anyone has seen anything like this with this.
