One thing I've noticed and it may or may not be related to the OP's issue is that as of mIRC 7.1, I cannot seem to save the minimized position of a send so that it will always open minimized whenever a script does a /dcc send unless that script includes the -m switch... and if it includes that and I change my mind and want it to save maximized, I'd again have to change the script(s) rather than right click on it and choose position > set as default. Either it worked differently before or somehow that setting was saved before because it always opened minimized from a script before 7.1 and now it always opens maximized. I think setting the default position as minimized on sends should keep it that way.
