I did a clean install of System 7.1 on my IIcx yesterday and then I proceeded to install Open Transport. OT is working fine but there is something strange going on with the TCP/IP icon in the Control Panels folder. Take a look at this screenshot: http://farm2.static.flickr.com/1306/1095790082_1b2ca39271_o.jpg.

Anyone seen this before?

Edit: I should probably mention that as well as installing OT, I installed the drivers for an Asante MacCon Nubus ethernet card and RAM Doubler. Dunno whether these may be the cause.
