Ouch! (NSISCONF.NSI)
Do many people here use NSISCONF.NSI? I decided to take advantage of it a while ago, and then upgraded NSIS to a new version without thinking it would overwrite my NSISCONF.NSI.
When I first noticed it had been reset I couldn't work out why it happened, because I upgrade NSIS all the time and nothing really ever seems to change - all the extra files in my folder stay there, so that creates an illusion. So I built it again, and when I re-upgraded NSIS,
'I can't believe I did that again!'
I think that it definitely shouldn't be overwritten when upgrading. This just defeats the purpose of having one in the first place if it's going to be defaulted every upgrade.
