Here's a recipe to slow down editing cells etc. in Calc considerably:

- open a new spreadsheet
- test Calc by just clicking on different cells and note that you're getting immediate location changes etc., with no delay at all
- then, press CTRL-A to highlight all cells and change the font from the standard font of your template to another one (in my case, that was from Times New Roman to Lucada Console)
- now, test Calc again by just clicking on different cells and note that you're getting long delays until Calc highlights the new cell, maybe nearly a second or so.

That can't be right: it makes editing superslow!

issue confirmed under Win7x64 as well with 4.2.4.2 and 4.2.0.4
not reproducible with 4.1.5.2, hence regression.

you don't need to type into cells to reproduce the bug, it seems that the slow down is triggered just by selecting all cells and then change font.

1- open blank Calc sheet and random click to any cell to see the correct speed of selection
2- click Edit/Select all and then change font from the dropdown menu
3- do again random click on cells and you will see slower cell selection highligting

If you just change the font from the menu without doing "select all" before, you won't see any change of speed.

the problem, however is not present anymore in 4.3.0.1.0+

TinderBox: Win-x86@42, Branch:libreoffice-4-3, Time: 2014-06-23_07:41:56

so the issue has been fixed in the 4.3.x branche so I'll mark this as RESOLVED WORKSFORME

anyway I add Calc developer to CC list to hear if this problem could be fixed in the 4.2.x branch as well.
