Calc. Whe I hit CTRL to open the cells are all very small. Ver. 4.3.7.2

See question.

Ctrl+Mouse wheel changes the visualization scale. Maybe this is the source of your problem.

I had the same issue, then I drag the zoom slider to 100% and the problem was gone, even I open a new calc file.

LOLAX: that did it…THANKS. Hawk63
