I current use the script console to test a REST wrapper implemented in Ignition using the system.net.httpclient.

Since upgrading from 8.0.7 to 8.0.11 (and subsequently 8.0.12) trying to create the httpclient fails inside the script console.

```auto
# Create the JythonHttpClient
client = system.net.httpClient()

Edit:  
Followed advice from [System.gui.transform error](http://forum.inductiveautomation.com/t/system-gui-transform-error/34253) and reinstalled designer. It seems to have fixed it.
