Vaio Laptop - XP2 - 512mb ram

Been using 1.5 for a while now and been totally stable. The other night I was playing at a gig in London and the screen started to go stuttery (like background tasks being done) checked - nothing was running in the background, no wifi, defragmenting etc. Went back to the Serato screen, the virtual deck started going made- the play arm that rotates started to multiply so I had loads of play arms if that makes sense. Thought I would go to the set up and change bufer size - clicking the set-up button made the machine finally hang and then I get an error on screen with (what I remember) Sub Routine Error x000000x00000 (not exactly this but hopefully you can get some sense from that). Restarted Laptop and then launched 1.5 and all worked well from there.

The ONLY thing I can think of is that I have very little hard disk space (partitioned) left but I do run a defragmenter (I have NFTS formatting so no problems) when I am not using Serato. This is the only thing I can think of. I also had center scroll on and remember scrolling quite qickly thru stuff so again maybe that caused it. Sorry I cannot be more explanatory but I was gigging and had to get my small CD back up running - quickly!
