[RTTY] Unidentified error box in MMTTY

[HANKKIER at aol.com]

Out of the blue yesterday, when I started MMTTY, a dialog box popped up in 
the middle of the screen labelled "Error". inside the box was "KF2O.MDT followed 
by a bunch of gibberish characters". I clicked OK, the box went away,  and 
MMTTY seems to operate normally. did it several times, including a reboot  of 
the computer in one of them. always starts out with the crazy error box.  then I 
downloaded MMTTY from the website, overwriting the same version. still the 
same error box keeps coming up. any idea what is in error? how to fix? Hank
