Help with error message

[raptor1810]

Hi;

Can someone tell me the meaning of this error message?

Error (RT) in SampleMacro:  the point is not in the window. 

I get these if I am working on the PC while the macro is running.  I understand this is probably because I move the mouse at the moment the macro starts.

But I also get them when my PC is running without me at the keyboard.  This is puzzling.  Any ideas on how to mitigate or debug this problem?

Thanks very much
