Just got over an interesting issue.... Though nothing was logged Processguard was causing a software install program, and then the program it installed (After PG was disabled) to halt with the only message being "Invalid Handle". Scanned logs, and nothing was found to cause this in PG, so I beat my head against a wall for a while longer, until I decided to turn stuff off. It was PG, and disabling it worked... Later on, (at someone else's suggestion I'm sorry to say), I tried Learning mode, and ran the programs again. Now All seems fine... ?? Have you ever encountered an issue like this? Can you provide insight as to what "Invalid Handle" means? Thanks!! Keep up the good work!!!
