WebDev 19 - FileDisplay (download) stopped working Windows 2008 R2

Hi anyone

I am using FileDisplay to initiate downloads. This *was* working but I not get a few strange "Connecting.." messages and it fails.

I assume that this is a Windows issue - but maybe some Windows update is not compatible with WebDeb 19 FileDisplay (or something .. !?)

Anyone seen anything remotely like this or any suggestions about how to debug this. The remote server has been rebooted. Everything looks OK. NO code changes ..

I'm grasping at straws at the moment ..

Thanks
Derek
