[Lowfer] Status report about Argo on XP and slow PCs

Thu, 28 Nov 2002 12:03:32 -0500

Alberto,

I have noticed some crashes here occuring after 48 hours of continuous use.
The screen would show several solid horizontal lines. I have been running in
30 second dot mode when this happened and with the automatic screen
capturing enabled. My setup here is an Athlon 550 MHz proceesor, 512 MB ram,
and running Win 98 SE. I have downloaded your test file and presently
running it. Will advise if there are any bugs or crashes.

Thanks for the updates.
