Cannot leave HELP with EXIT nor F1-key, calculator stuck in HELP menu

Hello,
when I am in the HELP menu, I cannot leave it with EXIT-key or F1 key :-(. Not even auto-turn off helps. What now, is my DM42 bricked? I can only change to the original help file of DM42.
Mario.

Call user program from within another

Having trouble when calling one user program from within another
First program is COUN : 2 SWAP PWR 1 - END
Second is VTOC : COUN * SWAP / END (have also tried with an XEQ after COUN)

Calling COUN works as expected, ( 16 -- 65536 ), but VTOC gives me the NO PROGRAM message. Is there something else I need to do to use COUN within VTOC?

BMP display offset

I borrowed your BMP display code and noticed the image was slightly offset. I had to change (50-j) to (49-j) in the line below. Reviewing the code, this looks like it is what it should be (to me anyway :-).

for(byte j=0; j<50; j++) d[j]=~bmp[(129+i*52)+(50-j)]; // INvert and flip
