This is really weird,
I went to use Winwarbler on RTTY this evening and the XY tuning indicator wasn't appearing nor was I able to copy anything. I went to Configuration and then to Rtty Configuration tab and all of a sudden the MMTY setup button is greyed out. I rebooted everything and it is still the same.
I went to Launcher and it had the "restore" button highlighted for WW, implying that WW had somehow gotten corrupted, but when I clicked on it, I received a message to the effect that it cannot delete the old program and operation aborted.
PS I used WW yesterday.
