Function names like BITVIEW or ROTXY seem to refer to a different ROM. I had the Advantage ROM installed. After removing this, everything works fine. Now only TVM 1E and the P#4 library are installed.

You had an XROM conflict because the TVM uses the same number as one of the Advantage pages. Simply removing the advantage solves it, as you did. As I said before, the TVM$ Module also has a copy of the Advantage's TVM so you don;t need to have both plugged in. Ditto for the PPC's "FI" and 'FIN" programs - they're also included in the TVM$ Module.

I am using V41 version 8 with default speed settings, which runs faster than my hardware 41CV. However, I noticed that after 4 seconds the "Running..." display flickered a few times.

The LCD flickering is intended - it does it each time a new iteration begins.

I admit I would not have expected times near 10 or 20 seconds on V41. This would translate to about 15...30 seconds on a physical '41. Do you think there is something wrong with my V41 setup?

The speed depends on the selected settings, I imagine you have already seen that in V41 configuration screens. You can always press the TAB key when the program runs to engage the TURBO mode - regardless of the settings - while you KEEP it pressed.
