1900D Freezes

[Meeko 17]

I purchased to 'D' last night. It's a bit of a change from the larger aircraft in my collection. My first flight wasn't much of a success. After a 60 mile journey, and on finals, my screen locked up and there was simply no way out but to press the reset button on my computer box. I was in VC at the time. As it froze up some warnings sounded. Yes, I have done a search and there was very little on this point. I read a post written by JiBrady (11 Feb 04) who had a similar problem but it was never resolved on the forum.Is this a known issue, and if so, do you have any suggestions of a work around?My system isAthlon 64Bit 3200+ Socket 939 processorGigabyte GeForce 7800 GTX 256MB card2GB DDR 400 RAMSeagate 200GB hard driveCreative Soundblaster Audigy 2 sound cardRegardsBruce Ross
