Hi folks, the line: if getMouseButtonPressStream^ .getLastEvent^ .getTarget = fLastEvent^ .getTarget then results in an error message: alpevents.pas:1255: error: invalid type of argument of `^' The error message disappears if I change the line into: if ( getMouseButtonPressStream^ .getLastEvent )^ .getTarget = fLastEvent^ .getTarget then What's that? Regards, Markus
