ProgressBar window "KeePass - Synchronizing..." has Cancel button disabled and "X" close button does no action, too. This sometimes leads to dead end.
On my machine, file sync sometimes cannot proceed, although before sync step, there is a check for server availability. When problem happens, progress bar is stuck exactly at 5%. I assume that first 5% is some sync preparation. So when such a freeze happens, "Cancel" is disabled and pressing "X" button makes window fade and Windows indicates that the application is unresponsive. There is no other solution than killing the KeePass.
Would you add possibility to cancel the sync and/or sync timeout?
