I am running supercontainer on a Windows Server 2008 with FMS 11 using a FMA11 client on a Macbookpro to access via VPN.

I am using SC 2.77 to store photographs. Upload and viewing usually is without consequence. The viewer is set to readonly.

Unpredictably I will access a record and see in viewer that SC is being accessed but just a white web viewer results. Switching records does not help. Switching layouts with a different size web viewer using same URL pointer usually reloads the related photograph into web viewer. Quitting and restarting client always restores function.

Also I occasionally get a java heap error that is always worked around by switching layouts which both contain the same web viewer pointing to the same URL. I do not get the java heap error with the "white" screen.

I have not tested to see if the behavior also occurs on a windows client, but I have not received user complaints.

Anyone know what is going on? How to fix?

I believe what you are expreiencing is a known issue with SuperConainer which happens when the web viewer is reloaded quickly. This is something which I think has been resolved internally and should be fixed in our next update of SuperContainer.
