I noticed now that on my x64 Vista box, PaintDotNet.exe is 32-bit.
C:\Program Files\Paint.NET>filever PaintDotNet.exe
--a-- W32i APP - 3.10.2791.35943 sh 901,120 08-23-2007 paintdotnet.exe
Well I figured maybe it was like Sysinternals stuff and it extracts the x64 version out of the x86 version, but all I'm seeing is the 32-bit version, even in process explorer.
Now there is a Shell Extension that is x64 (probably for the right-click context menu) and some "squish" dll.
Did you guys abandon the x64 build? Admittedly I haven't checked since the 2.x days, but I could have sworn it was an x64 exe back then...
