I’ve had this issue for several years and I’ve just restarted UFT or rebooted the PC.
I have several functions that override the native methods for Set, Select, Click, etc. The reason I do this it perform extra reporting and a data check on the method. I think that UFT gets lost in the registering and unregistering of the functions but I’m not sure. Once I reboot, everything works for a while. It could be hours or days and then I’ll get the error message. Can you help so I don’t have to restart UFT?
