My Service Management window always freezes whenever I preview a work order. Does this happen to anyone else? If so, does anyone know how to fix it?

If I click the "close preview" button (rather than clicking the red X), it will then close the preview (as it should), but in-so-doing will also lock up my whole service management module.  I have to force it closed through task manager in order to remove it from my screen.  This happens to everyone in our office.  Any suggestions?

(I don't know if this matters, but we are connected remotely through Swizznet)

This happens in version 15.1
