I mean doing the trace by either method, either the TC EIP<900000 at the command line first mentioned in LaBBas tuts, or when doing the memory (on execution) breakpoint on the app's code section and then pressing ctrl & F11.
On some programs it just keeps hanging on the trace, and last night I left it for some considerable time on TweakRAM, it still showed tracing in the bottom right, but I'm sure it had hung.
