I am working on an older RMX 1000 Version 1.1.1 and after some period of time the Internet explorer will stop working with the Web UI. When you click on anything in the UI it just pops up a blank box with and X in the upper left corner of the window. Logging out of the Web UI and closing the browser seems to resolve the issue every time. Running IE 8. Have tried compatibility mode as well. Any suggestions?
