Ick, thats one of the first things i turn off in any app that supports it, waste of resources.
They should concentrate on fixing the bugs, I can't seem to save images from web pages for one. Perhaps its time to grab a nighlty, as im still using 0.5
if its what I think it is, then instead of just scrolling "as-is" so to speak, it processes how much you've scrolled, then actually carries it out with a smooth action, but delayed.
Ok, so its not going to slow your entire system to a grinding halt, its just one of them things that I find annoying
also, how do i go about "upgrading" phoenix, at the moment i have 0.5 unzipped to F:\programs\phoenix
and I'm downloading the nightly zip, how do I keep all my settings etc?
hurah, with phoenix (and mozilla probably, but you'd need to turn quick launch off..) you could download, un-zip, copy to your normal phoenix dir with the "/Y" switch, automatically overwriting your current version, then delete the temp files.
set the .exe to run every 2 days at 5am or whenever (if you leave your computer on..) and you'll always be current
as for the actual development, I think its pretty random, not really sure though.
