HI guys, I have a tough one which i was very surprised to experience, and its ridiculous(!), so i really hope you can help solve it.

I have a 13" Samsung Series 9 touchscreen laptop, purchased in 2015. Running Office 2013. When i zoom out of a document in MS Word, say by clicking the minus on the slider in the bottom right, its silky smooth. Each click the zoom goes to 90%, to 80%, to 70% and each time the text appears a little smaller, as you would expect.

When i zoom out of an Excel worksheet (just text and numbers, Arial size 11, no macros, no formulas), the text size wont change for several clicks... 100% to 90% to 80%... then i click down to 70% zoom, and all of a sudden the text goes to about 30% of its original size. Keep clicking to 60%, 50%, 40%, 30% zoom - the text size doesnt get any smaller. Then to 20% and bam- its tiny. For each change in zoom the grid of worksheet cells appears smaller, as you would expect. Its just the text that makes these big erratic jumps. Any thoughts on this?

Cheers, Andrew
