I have recently been experiencing a problem with a few seconds delay when adding or deleting elements.

I have no idea if this is hardware or software related but I have not changed my hardware and the only software changes have been updates to OS, programs or drivers.

I know that this is really vague but was wondering if there was a setting somewhere or something that someone could suggest I look at to overcome a very frustrating and counterproductive issue.

Any suggestions would be most welcome.

Many thanks
