Conditional formatting

Conditional formatting

Hi,

I have a spreadsheet with conditional formatting on each cell. I wand to change the cell color as soon as there is a value in the cell.
Now all works perfect, except.. when I close the browser and reopen the spreadsheet the conditional formatting is not active anymore. Although the rules are still there.
I have to open the conditional formatting dialogue, where I can see all rules and click ok. At this point the conditional formatting gets active.

Please help.

thanks Ernst
