Unable to Pause or Sleep after Select-Object

In some cases, if I try to pause or sleep after a Select-Object command, the pause/sleep occurs before the command.

For example, with

Get-NetAdapter | Select-Object Name,Status
Pause

or

Get-NetAdapter | Select-Object Name,Status | Where-Object {$_ -ne $null}
Pause

the output is:

Press Enter to continue...:

Name     Status
----     ------
Wi-Fi    Up
Ethernet Disconnected

Whereas with

Get-NetAdapter | Select-Object Name,Status | Format-Table
Pause

the output is:

Name     Status
----     ------
Wi-Fi    Up
Ethernet Disconnected

Press Enter to continue...:

What’s going on here? Is this a bug or a feature?

I can’t replicate your issue. Are you testing in Powershell ISE? My assumption is you are seeing the script posted to the output window which would appear as though it processed your script?

#cls
$procs = Get-Process
"There are {0} processes running" -f $procs.Count
Pause
"Doing more stuff"

Output:

PS C:\WINDOWS\system32> $procs = Get-Process
"There are {0} processes running" -f $procs.Count
Pause
"Doing more stuff"
There are 98 processes running
Press Enter to continue...: 
Doing more stuff

Output with Clear-Host (cls) at the top:

There are 98 processes running
Press Enter to continue...: 
Doing more stuff

As I said, the above ran Get-Process, wrote output to the host, paused until I hit enter and then wrote the final host message.

Apparently this is only happening in v5. I posted this on StackOverflow as well:
