I just upgraded to 7.1.6. Using Windows Server 2012, I was switching back and forth between different RDP sessions. On two occasions, when I RDP'd back to the Server with Visual Cron on it, the Visual Cron interface was frozen. There was nothing I could do to get it to release. One time, when frozen, I eventually got a "Visual Cron Must restart box". Not sure if I caused it or whether it happened after time.

Here is the error log:

An unhandled error has occured (please send the information below to support@visualcron.com):

It "might" be related to a control that we use for UI, Infragistics, we will be upgrading this control for the next version (7.1.7.). It would be interesting if you could test if it works better there. You can try this build here:
