NT 3.51 was the MOST stable version of any NT based Operating System to date if you ask me.
To be honest Alec out of all the versions of Windows I think NT 3.51 and sub 3.0 are the only versions I've never used. I've used Windows 3.0, 3.1, 3.11, Win95, 95A, B, C, 98, 98SE, NT 4, WinME, Win2K, and WinXP. In fact I had a 386 up until early 1996 and still used Win 3.11. Which means I have no fear of a command prompt

. I will have to take your word it on the stability bit, because I've never used it.
It also doesn't surprise me that Progman.exe and WinFile.exe are extremely stable components they've been around for years and are tried and true. They also don't do much, which means there's not much that can break or slow the system down. I still think WinFile with two horizontally stretching window panes is a tough file manager to beat. I use PowerDesk when I miss the dual pane beauty, but WinFile sure was fast. Unfortunately that crashes all the time so I'm not a big fan. I imagine you have it or have used it in the past since you've got Mijenix SystemSuite. I suppose your's is Ontrack's though since it's 4.X. Although now the suite belongs to V-COM

. My dad just recently bought Acronis's PowerTools. Have you ever used it? It's not particularly good at anything it does, but it basically does every major feature that system utilities offer.
#1. Backup
#2. Partition Resizer
#3. Boot Manager
#4. Virus Scanner
#5. Virtual CD/DVD Drive Emulator
#6. Data Wiper
#7. Data Recovery
#8. Performance Optmizer
I've only used the Partition Resizer, Boot Manager, and Backup Utilities. The backup utility is pretty cool, it works inside of windows, which is a double-edged sword I suppose. The Parition Resizer sucks, because it only supports Fat16/32 conversions. It will however let you size your clusters at whatever size will give you the most disk space. Since I'm low on disk space I comprimised a little performance for another 500MB disk space on my 8.5GB OS/Application Partition.
he's not using the Win3x shell & programs, that would not be prudent OR possible I don't think
Actually he is using the Win3X shell, that's exactly what Progman.exe is. Sure it's been retrofitted a little to work with Win32, but it's still essentially the same program. I don't think he's trying to run Win16 apps, but he may be doing that too, since his behavior is characteristic of someone who misses Win16's simplicity. Which every now and again I do too

.
Oh also How's the next version of APK Tools coming along? Did you get everything working with InnoSetup?
Adios Amigo,
