Can someone tell me if hardware Watchdog is implemented in Webmite 5.07.08b4 ?
I know that it is there for the Picomite, but when I try in this version of Webmite it returns a syntax error

WatchDog hw 8000
Error : Expression syntax

So I loaded WebMite MMBasic Version 5.07.08b14 and the hardware watchdog seems to work.......mostly.

Occasionally the program stops running altogether, a power cycle does not restart it. When I telnet into the Webmite I find that all the options have been cleared, although all other files are intact.
Enter all the options again and run the program, everything works.

I haven't been able to tie down what exactly is happening, just wondering if anyone else has experienced the "disappearing options" problem.

That doesn't compute. If you can telnet then all the options haven't been cleared.

Use the HW watchdog with discretion with web applications. The maximum timeout is 8.3 seconds and if a web activity hasn't completed in that time you will get a timeout with unforeseeable consequences

I guess hardware watchdog is just not suitable for my application.

This is similar to what I observed (as described here).

I am running now beta b12 (with the software WATCHDOG), but I tried other betas (<=12, also with the HW WATCHDOG) and the last release. The problem persists; under some circumstances, the WebMite loses all options and the programs in the flash slots are lost. Drive $A is still o.k.

Random observations:
- with b12, I have not observed a crash within a week or so.
- still, when I disconnect the WebMite from power w/o stopping the software, it often (50% of the cases?) looses all settings (as described above).
