Move appointment to Folder - Freezes

I have several calendars synced, When I try to move an appointment to a folder (trying to move to a different synced calendar) it just freezes everything. I have to open task manager and end task, re open and wait for it to verify data before I can get back into the software. 

So I guess the question is how can I move an appointment from one calendar to another.

What version of eM Client and Windows are you using Roger?

7.2.34062.0

The second I click on the folder on the bottom of the appointment everything locks solid and I have to end task in the task manager. Currently using version 7.2.35128.0
