"Synchronisation Status" - Windows can not be closed

[Hambrecht]

Our Internet goes down several times a day for 3 or 5 minutes.
When this happens - the window for the "Synchronisation-Status" with the EPIM-Cloud remains open - and does no more close.
You can click anywhere, this message window doesn't close - only if you kill the entire program in the Task Manager.
Even if the internet connection is up again, this window hangs.
This problem is starting to annoy me. Can you fix this error?

What's the EPIM version number? Also, what will happen if you click on the Hide button or select the current task and click on the Stop Task one?
