Hi Catherine.
Thanks for posting on the forum.
Does this also happen outside of ActivInspire? In programs such as Microsoft Paint?
What model of ActivBoard are you using? The product code will be on the left hand side of your ActivBoard just below the pen holders.
I noticed you have posted on another thread on how to disable touch, please let me know if that helps with the issue you are experiencing.
If that helps, I would recommend contacting Promethean Technical Support either directly via phone: http://goo.gl/tzNWci or use the contact form: http://goo.gl/pqrGC2 and mention the case number which I've created to support the issue you are experiencing. The case number is: 00425341.
