Change it to what ... something inherited from some other app?Internal commands & externals called from recursive internals (like GLOBAL) always change the title.
TITLE /P %TITLEPROMPT & GLOBAL PAUSE
Well I don't. I tried it thinking that you had suggested it might fix things. It didn't and it's gone now. What happens when you do this with TITLEPROMPT set and UpdateTitle=No?The only things I know of that could cause the kind of behavior you're seeing is if you have a TITLE or WINDOW command in your TCSTART.
WAD. If the command argument does not end with "tcc.exe" (and yours doesn't), TCC will not switch to the "TCC Prompt" default argument. This is by design, as otherwise if you specified a title when starting TCC (i.e., via sui.lpTitle) it would always be overridden with a default title.
