21richyrich,
best of luck to you - it certainly hasn't been the rocket ride I would have hoped for, but then maybe they may well be on the cusp of a genuine break-out and greater use of their technology? The critical issue for me is not debt or cash (both can be easily overcome) but the lack of any new 'deals' other than those we know of..to me that is its one and only significant weakness, and it also seems that I have been saying for far too long that they should have appointed top-flight sales/marcoms people by now...
Still, as has been said, this could still be a multi-blagger - just don't bet the farm on it!
regards
T..
