Hello everyone. I have developed an application using VB.NET. It starts out working quite well and the speed is decent; however, if the application sets for a little while with no use or no action, then it slows down significantly. A matter a fact, just to tab from one control to another could take up to 3 or 4 seconds. Has anyone seen this problem? Or is there a service pack I am missing or something? Thanks for the help.
