This release finally fixes the plugin for modern HDT version (tested with v1.5.11)
Also includes a couple of new features:

• You can now press Alt + Ctrl+ D to enable/disable the plugin (the plugin will not retain the selected state after restarting the HDT)
• After 3 unsuccessful attempts to squelch the opponent, the plugin will now give up 😞
• After squelching the opponent, the cursor will be returned to its original position

Also the plugin should now work better for higher-resolution screens (hopefully).

Don't forget to UNBLOCK the dll file if you don't see the Autosquelch plugin in your list.
