Keith,
What type of content are you running? I know I’ve responded to a recent post (within the last week), of similar problems myself and another user are experiencing. I’m seeing similar symptoms but it’s only when running web content. 90% of what we run is web content, so Friday I implemented a scheduled task to terminate then restart the xibo client every 12 hours. This will fit well in my environment till the IE memory problem is resolved. I can say that other content that does not use IE (non web content) has been running like a champ on version 1.7.1, 1.7.2, and 1.7.3.
