Re: Hidden gem prevents flickering when displaying graphics

Thank you RAV!

Flickering animations while using ⎕WC have been "bugging" me for many years.

Your

Re: Welcome to the MiServer forum!

This forum states:
You can download MiServer from http://tools.dyalog.com.
When I try to access "tools.dyalog.com" I get the response
This site can’t be reached
Where is the current documentation on how to download the latest Miserver version (Miserver 3.1?)

Thanks
