It's when the property doesn't exist that it errors. It does not return .f., it produces an error, unlike PEMSTATUS(_screen,'Printscr',5) which returns false if the property does NOT exist. I believe it is a bug because the help file states that both should return .f. if the property does not exist. You cannot use 4 to see if the property exists or not because of the error.

>>Let's say it's been added using addproperty() to the _screen. Checking with '5' instead of '4' will return .t. Now if I check using '4' to see if it is user-defined, I still receive an error, not a false. How do you see if it is user defined without the error occuring?
