>>I have a very strange error occuring at one installation. My software is installed in over 2500 locations right now, but I'm only getting reports of this from one location.
>>
>>Basically, I have some code that is deigned to display a Yes/No prompt on the screen by creating an instance of a message box that I have created. The function parses some parameters, instantiates an object, and then sets various properties of the that object based on the parameters. In one location, I am getting halfway through the code that sets the properties of the message form, and then errors out with an "oTouchMessage is not an object" error. I enabled detailed logging including a memory dump and it shows that the value of my object has reverted to null. This is very odd because it happens after I have set 3 or 4 different properties of the object in code. It doesn't happen every time, but it always happens at the same line of code if it is going to happen.
