I've had several screen lockups, but it wasnt just with Mindano... I have been getting them since the 1.07 version came out. Thought it was a heat problem, but nothing else does it- replace the power supply and still get them occasionally. They seem to happen more frequently with RW up, so I don't use it anymore.
T-bird 900, Geforce2MX with the latest drivers (12.whatever), latest Via 4in1s, some crap mobo soundcard and 256 mb RAM. Also use cable, dunno how that would affect it tho.
