16932	Microsoft Office unusable in version 5.1.24, was working in 5.1.22 fairly well, not perfect though	Rafcio		"After installing the latest VBox (5.1.24) the guest becomes unusable when Microsoft Office is running. It becomes completely unresponsive. The clock (showing seconds) no longer advances by 1 second, instead it jumps every few seconds showing that the VM is hung most of the time. The guest window even darkens periodically showing that the host detects it as unresponsive.[[BR]]

For some applications, it's enough to open it without loading anything (Word 2016 or Excel 2016 for example). The older versions (i.e. Word 2013 or Excel 2013) can be opened, but if a document is loaded, or in the case of Excel if any single cell (or a range of cells)  is copied to the clipboard, the guest becomes pretty much locked. It is possible with persistent clicks on the close button to terminate MS Office application and regain guest responsiveness, but this usually takes minutes as the VM pretty much doesn't respond for most of the time.[[BR]]

I have reverted to 5.1.22 and the problem went away proving it's a regression in 5.1.24.
