Ruby from the command line - sticking - Windows

I hav开发者_如何转开发e seen this behavior on Windows with Ruby for a long time. If I install a gem sometimes the command line will just get "lost" and stop printing output until you go back to the command line and hit enter a few times.

I notice this in other places too. Like starting up a Ruby on Rails console. Or generating a model with Rails.

Have other people seen this? What causes this? The weird thing is this doesn't happen all the time.

I have never seen this with PHP, Lua, Perl or Python from the command line.

I have seen this on Vista and Windows 7 (32-bit and 64-bit). This happens on multiple machines.

Did you try to copy any text from the command window before this happened? The Windows console gets locked if the select mode is ON (i.e. if you selected some text in the console and switched the window)
