Yes, I have seen that problem, too - many months if not years ago, so whatever causes this problem RISC OS 5.13 is not to blame. Every now and then saving an e-mail in MPro caused a total freeze. The problem has gone away at some stage and it was never established what caused it. Basically, any significant system change (e.g., installing a new module in your boot sequence) causes memory locations to change, so the effects of a bug in some piece of software could change from harmless to a system freeze. Obviously, installing a new version of the OS is a big change.
