It won't fill file name box with custom text/filename.
Thanks this issue has been fixed for the next version.
Now we have two windows for $sdir?
This has always been the case. mIRC attempts to use several types of file dialogs and if one type is not available (depending on the Windows version), mIRC tries an older type. In this case, the new file dialog fails to initiate because of the invalid path name, so mIRC assumes it is not available and defers to an older type, which appears to ignore the bad path name and allows you to make a folder selection.
Update: I have found a way of getting around this issue - if the new file dialog fails due to a path error, mIRC will retry the dialog with an empty path (which appears to be what older dialogs do by default).
