Office Excel Macro don't show the same like Excel do

Hello Atlassian,

we're using confluence 4.3.2 and Office Connector plugin 2.1.10 .
Now we received some problems with embedded excel sheets.
The viewed sheet is getting some information from another sheet in the same excel file but instead of showing any Numbers it shows " #REF! " .

Next topic is that the macro don't care about if we adjust in excel to show only one decimal place. It still shows all decimal places.

Excel files which are bigger than 3MB will not be viewed.

Is there any way to solve this problems or will there be a fix in a future version of the plugin?

Thanks in advance
Jan S.
