Under certain circumstances, when Write-Progress is used in Windows PowerShell ISE and a new tab is opened, the Write-Progress output does not display properly. Closing tabs makes it appear.

Always Happens

No, this is new to the most recent version

1. Run "powershell_ise.exe -noprofile"
2. Paste the following code in the script pane:
    $i = 1..100
    $i | % {
        write-progress -Activity "Testing Output" -Status $_ -PercentComplete $_
        sleep 1
    }
3. Note the progress bar works properly
4. Open a new tab by pressing Ctrl+T
5. Switch back to the first tab
6. Note the progress bar continues to works properly
7. Close the second tab
8. Open a new tab by pressing Ctrl+T
9. Switch back to the first tab and note the progress bar is missing
10. Close the third tab
11. Note that the progress bar displays properly again

The progress bar from Write-Progress is displayed regardless of the state of the tabs in the ISE.

This is very annoying when you have something that takes hours to run and you lose the progress bar. I hope they will fix this at some point before V4.
