Hello Ambient2002,
This issue has been addressed and fixed in the latest version of CVI 7.1. It seems like the issue occurred with the older operating systems (95/98/Me). I would suggest updating your operating system or using NT/2000 if upgrading CVI is not possible. If none of these choices are acceptable, I would suggest trying this workaround which has worked for some customers: "the resources are leaked in the call to HidePanel. This can be avoided by calling ProcessSystemEvents before the call to HidePanel takes place, or activating a second panel before hiding the original panel."
Thanks!
