Are you sure you understand how to edit those types of templates?  That old style of template from the 1990s is annoying to edit because you can't just put !1 and !2 wherever you want when editing.  You have to edit the ANS file after you save it and place the codes at the end using location codes to locate them (or add them last using animated mode in TheDraw).

I have an ansimlst_c132x36.ans on my BBS that is working fine for me.   If you have a specific reproducable issue I can take a look at it if you want to.  You can e-mail me the ANS file to mysticbbs on gmail and I'll look into it next time I try to get caught up on emails.

... I'm not a complete idiot... Several parts are missing!
