Having a most annoying bug in XL while connected to the internet. When we are running XL & internet at the same time a mysterious "De-selection Bug" sometimes appears. Basically, whatever cell is selected is automatically deselected after what appears to be a set period of time, which means I must Re-click the cell, sheet or reselect selected cells and all functions & macros are slowed down or lost (require debug) completely. The bug only appears while connected to the internet, no viruses or other unusual behavior have been detected. The only solution I have at the moment is to break the internet connection and then it stops, XL works normally.

Any help, comments, would be much appreciated.

Thanks
