While I love Access and have done for more than twenty years, I have for perhaps the last 5 years been troubled by it going slow when going into design mode, sometimes slow to the point of being unusable 
Strange thing is that the problem will usually clear itself within a few weeks and everything return to normal.
There are plenty of people complaining about the issue on the web and the odd bit of advice, now of which has worked permanently.
If any kind soul could put me out of my misery then that would be hugely appreciated. I have attached a X+Zipped Powerpoint file that illustrates the issue better than I can describe it. Sometimes it is even worse than what you see here.
Many thanks for listening! ..... Keith
